備份 Hyper-V 虛擬機器Back up Hyper-V virtual machines

System Center Data Protection Manager (DPM) 藉由備份虛擬機器的資料來保護 Hyper-V 虛擬機器。System Center Data Protection Manager (DPM) protects Hyper-V virtual machines by backing up virtual machine's data. 您可以備份 Hyper-V 主機層級的資料,以啟用 VM 層級與檔案層級的資料復原,或備份客體層級以啟用應用程式層級的復原。You can back data up at the Hyper-V host level to enable VM-level and file-level data recovery, or back up at the guest-level to enable application-level recovery.

支援的案例Supported scenarios

下列案例中,DPM 可以備份在 Hyper-V 主機伺服器上執行的虛擬機器:DPM can back up virtual machines running on Hyper-V host servers in the following scenarios:

  • 具有本機或直接儲存空間的虛擬機器:備份裝載在 Hyper-V 主機獨立伺服器上具有本機或直接連接儲存空間的虛擬機器。Virtual machines with local or direct storage - Back up virtual machines hosted on Hyper-V host standalone servers that have local or directly attached storage. 例如︰硬碟機、存放區域網路 (SAN) 裝置或網路連接存放 (NAS) 裝置。For example a hard drive, a storage area network (SAN) device, or a network attached storage (NAS) device. 所有主機都必須安裝 DPM 保護代理程式。The DPM protection agent must be installed on all hosts.

  • 具有 CSV 儲存空間之叢集中的虛擬機器:備份裝載在 Hyper-V 叢集上具有叢集共用磁碟區 (CSV) 儲存空間的虛擬機器。Virtual machines in a cluster with CSV storage - Back up virtual machines hosted on a Hyper-V cluster with Cluster Shared Volume (CSV) storage. DPM 2012 SP1 引進了快速完整備份、平行備份,以及 CSV 備份的叢集查詢改善。DPM 2012 SP1 introduced express full backup, parallel backups, and cluster query improvements for CSV backup. DPM 保護代理程式會安裝在每個叢集節點上。The DPM protection agent is installed on each cluster node.

  • 具有 SMB 儲存空間的虛擬機器:備份裝載於 Hyper-V 獨立伺服器或具有 SMB 3.0 檔案伺服器儲存空間之叢集上的虛擬機器。Virtual machines with SMB storage - Back up virtual machines hosted on a Hyper-V standalone server or cluster with SMB 3.0 file server storage. 獨立檔案伺服器或檔案伺服器叢集支援 SMB 共用。SMB shares are supported on a standalone file server or on a file server cluster. 如果您使用外部 SMB 3.0 檔案伺服器,則 DPM 保護代理程式應該安裝在其上。If you're using an external SMB 3.0 file server the DPM protection agent should be installed on it. 如果儲存伺服器已叢集化,則代理程式必須安裝在每一個叢集節點上。If the storage server is clustered, the agent should be installed on each cluster node. 在 SMB 共用上,您需要有應用程式伺服器之 machine$ 帳戶的完整共用與資料夾層級權限。You'll need full-share and folder-level permissions for the machine$ account of the application server on the SMB share.

  • 備份設定即時移轉的虛擬機器:即時移轉可以讓您在移動某個位置的虛擬機器時,同時能不受干擾地執行存取。Back up virtual machines configured for live migration - Live migration allows you to move virtual machines from one location to while providing uniterrupted access. 您可以在兩部獨立的伺服器之間、在單一叢集內,或在獨立與叢集節點之間移轉虛擬機器。You can migrate virtual machines between two standalone servers, within a single cluster, or between standalone and cluster nodes. 多重即時移轉可以同時執行。Multiple live migrations can run concurrently. 您也可以執行虛擬機器存放區的即時移轉,讓虛擬機器在移到新儲存位置的同時,還能繼續執行。You can also perform a live migration of virtual machine storage so that virtual machines can be moved to new storage locations while they continue to run. DPM 可以備份針對即時移轉設定的虛擬機器。DPM can back up virtual machines that are configured for live migration. 閱讀其他資訊。Read more.

  • 備份複本虛擬機器:備份在次要伺服器上執行的複本虛擬機器 (僅限 DPM 2012 R2)。Back up replica virtual machines - Back up replica virtual machines running on a secondary server (DPM 2012 R2 only)

主機與客體備份Host vs Guest backup

DPM 可以執行 Hyper-V VM 的主機或客體層級備份。DPM can perform a host or guest-level backup of Hyper-V VMs. 在主機層級,DPM 保護代理程式是安裝在 Hyper-V 主機伺服器或叢集,保護該主機上執行的全部 VM 和資料檔案。At the host level the DPM protection agent is installed on the Hyper-V host server or cluster and protects the entire VMs and data files running on that host. 在客體層級,代理程式是安裝在每部虛擬機器上,保護存在於該機器的工作負載。At the guest level the agent is installed on each virtual machine and protects the workload present on that machine.

兩種方法各有其優缺點︰Both methods have pros and cons:

  • 主機層級備份有彈性,因為它們不理會客體機器執行何種類型的作業系統,因此不需要在每部 VM 安裝 DPM 保護代理程式。Host-level backups are flexible because they work regardless of the type of OS running on the guest machines and don't require the installation of the DPM protection agent on each VM. 若部署主機層級備份,就能夠復原整部虛擬機器,或檔案及資料夾 (項目層級復原)。If you deploy host level back you'll be able to recover an entire virtual machine, or files and folders (item-level recovery).

  • 如果您想要保護在虛擬機器上執行的特定工作負載,客體層級備份就很實用。Guest-level back is useful if you want to protect specific workloads running on a virtual machine. 主機層級可以復原整部 VM 或特定的檔案,但不會復原特定應用程式的內容。At host-level you can recover an entire VM or specific files, but it won't provide recover in the context of a specific application. 例如,為能從備份的 VM 復原特定的 SharePoint 項目,您應該執行該 VM 的客體層級備份。For example to be able to recover specific SharePoint items from a backed up VM then you should do guest-level backup of that VM. 請注意,如果您想要保護傳遞磁碟上儲存的資料,則必須使用客體層級的備份。Note that you must use guest-level backup if you want to protect data stored on passthrough disks. 傳遞允許虛擬機器直接存取儲存裝置,請勿將虛擬磁碟區資料存放在 VHD 檔案中。Passthrough allow the virtual machine to directly access the storage device and don't store virtual volume data in a VHD file.

線上和離線備份Online and offline backup

重要

視您的 DPM 設定及要保護的項目而定,DPM 的線上和離線備份行為會有所不同。Depending on your DPM configuration, and what you are protecting, DPM's online and offline backup behavior differs. 如果您使用包含 UR3 的 DPM 2012 R2 (或更新版本 ) 來保護 Windows Server 2012 R2 (或更新版本) 上的 Hyper-V,則 VM 在備份程序期間會繼續執行。If you use DPM 2012 R2 with UR3 (or later) to protect Hyper-V on Windows Server 2012 R2 (or later), the VMs continue running during the backup process. 若為此情況,則不適用此節的其餘部分。In this case, the rest of this section does not apply.

如果您是保護 Windows Server 2012 上的 Hyper-V 伺服器,或如果您使用包含 UR1 或 UR2 的 DPM 2012 R2,則下節適用於您的設定:If you protect a Hyper-V server on Windows Server 2012, or if you use DPM 2012 R2 with UR1 or UR2, the following section applies to your configuration:

DPM 與 Hyper-V 磁碟區陰影複製服務 (VSS) 寫入器密切整合,以確保可擷取及保護一致的虛擬機器版本,而不會影響虛擬機器的存取。DPM works seamlessly with the Hyper-V Volume Shadow Copy Services (VSS) writer to ensure that consistent versions of virtual machines are captured and protected without affecting virtual machine access. 備份已開啟檔案的能力是商務持續性的關鍵。The ability to back up open files is critical for business continuity. 根據預設,DPM 會執行不影響虛擬機器可用性的線上備份。By default, DPM performs online backups that don't affect the availability of virtual machines. 若要執行線上備份,需要以下條件:To perform an online backup the following is required:

  • 必須啟用備份整合服務,所以在虛擬機器上執行的作業系統必須支援 Hyper-V 整合服務。The Backup integration service must be enabled, so the operating system running on the virtual machine running must support Hyper-V integration services.

  • 客體作業系統必須支援 VSS (Windows 2003 Server 或更新版本)。The guest operating system must support VSS (Windows 2003 server or later). 如果虛擬機器正在執行 Linux,則不支援線上備份。Online backup isn't supported if virtual machines are running Linux.

  • 虛擬機器上應該沒有動態磁碟。There should be no dynamic disks on the virtual machine.

  • 所有磁碟區都必須是 NTFSAll volumes must be NTFS

  • 不得修改磁碟區的 VSS 儲存體指派。The VSS storage assignment for the volumes shouldn't be modified.

  • 虛擬機器必須正在執行中,而且如果虛擬機器位於叢集中,則叢集資源群組應在線上。The virtual machine must be running, and if the virtual machine is in a cluster the cluster resource group should be online. 虛擬機器內磁碟區的陰影存放區指派不得明確設定為非其本身的其他磁碟區。A Shadow Storage assignment of a volume inside the virtual machine mustn't be explicitly set to a different volume other than itself.

如果不符合這些條件,DPM 將會執行離線備份,其中虛擬機器會在擷取快照集時暫停並處於已儲存狀態,而後虛擬機器會恢復。If these conditions aren't met DPM will perform an offline backup where the virtual machine is paused and placed in a saved state while the snapshot is taken, and then the virtual machine is resumed. 這表示在備份期間無法使用虛擬機器,在許多環境中通常很短期 (不到一分鐘)。This means the virtual machine is unavailable during the backup, usually a short period of less than a minute for many environments.

備份程序的運作方式How the Backup process works

DPM 會執行使用 VSS 的備份,如下所示:DPM performs backup with VSS as follows. 為了清楚呈現,這項描述中的步驟會依號碼列示。The steps in this description are numbered to help with clarity.

  1. DPM 區塊型同步作業引擎會製作受保護虛擬機器的初始複本,並確認虛擬機器的複本是否完整且一致。The DPM block-based synchronization engine makes an initial copy of the protected virtual machine and ensures that the copy of the virtual machine is complete and consistent.

  2. 製作並確認初始複本之後,DPM 會使用 Hyper-V VSS 寫入器來擷取備份。After the initial copy is made and verified, DPM uses the Hyper-V VSS writer to capture backups. VSS 寫入器會提供一組與 DPM 伺服器同步且資料一致的磁碟區塊。The VSS writer provides a data-consistent set of disk blocks that are synchronized with the DPM server. 這種處理方式提供使用 DPM 伺服器「完整備份」的優點,同時還能盡量減少必須透過網路傳輸的備份資料。This approach provides the benefit of a "full backup" with the DPM server, while minimizing the backup data that must be transferred across the network.

  3. 執行 Hyper-V 之伺服器上的 DPM 保護代理程式會使用現有的 Hyper-V API,判斷受保護的虛擬機器是否也支援 VSS。The DPM protection agent on a server that is running Hyper-V, uses the existing Hyper-V APIs to determine whether a protected virtual machine also supports VSS.

    • 如果虛擬機器符合線上備份的需求,而且已安裝 Hyper-V 整合服務元件,則 Hyper-V VSS 寫入器會以遞迴方式將 VSS 要求轉送到虛擬機器上的所有 VSS 感知處理程序。If a virtual machine complies with the requirements for online backup and has the Hyper-V integration services component installed, then the Hyper-V VSS writer recursively forwards the VSS request through to all VSS-aware processes on the virtual machine. 執行這項操作時,虛擬機器上不需要安裝 DPM 保護代理程式。This operation occurs without the DPM protection agent being installed on the virtual machine. 這種遞迴的 VSS 要求可讓 Hyper-V VSS 寫入器確保磁碟寫入操作保持同步,以避免擷取 VSS 快照集時遺失資料。The recursive VSS request allows the Hyper-V VSS writer to ensure that disk- write operations are synchronized so that a VSS snapshot is captured without the loss of data.

      Hyper-V 整合服務元件會在虛擬機器上叫用磁碟區陰影複製服務 (VSS) 中的 Hyper-V VSS 寫入器,確保其應用程式資料處於一致的狀態。The Hyper-V integration services component invokes the Hyper-V VSS writer in Volume Shadow Copy Services (VSS) on virtual machines to ensure that their application data is in a consistent state.

    • 如果虛擬機器不符合線上備份需求,則 DPM 會在擷取資料檔案之前,自動使用 Hyper-V API 暫停虛擬機器。If the virtual machine doesn't comply with online backup requirements, DPM automatically uses the Hyper-V APIs to pause the virtual machine before they capture data files.

  4. 在虛擬機器的初始基準複本與 DPM 伺服器同步之後,系統會在新的復原點中擷取對虛擬機器資源進行的所有變更。After the initial baseline copy of the virtual machine synchronizes with the DPM server, all changes that are made to the virtual machine resources are captured in a new recovery point. 復原點代表虛擬機器在特定時間的一致狀態。The recovery point represents the consistent state of the virtual machine at a specific time. 擷取復原點的操作一天可能至少會執行一次。Recovery point captures can occur at least one time a day. 建立新的復原點時,DPM 會使用區塊層級的複寫搭配 Hyper-V VSS 寫入器,以判斷在上次建立復原點之後,哪些區塊在執行 Hyper-V 的伺服器上已經更改。When a new recovery point is created, DPM uses block-level replication in conjunction with the Hyper-V VSS writer to determine which blocks have been altered on the server that is running Hyper-V after the last recovery point was created. 接著這些資料區塊會傳輸到 DPM 伺服器並套用到受保護資料的複本。These data blocks are then transferred to the DPM server and are applied to the replica of the protected data.

  5. DPM 伺服器會在裝載復原資料的磁碟區上使用 VSS,以便提供多個可用的陰影複本。The DPM server uses VSS on the volumes that host recovery data so that multiple shadow copies are available. 這些陰影複本各自提供一次個別的復原。Each of these shadow copies provides a separate recovery. VSS 復原點儲存在 DPM 伺服器上。VSS recovery points are stored on the DPM server. 在執行 Hyper-V 之伺服器上製作的暫存複本,其儲存時間只限 DPM 同步處理期間。The temporary copy that is made on the server running Hyper-V, is only stored for the duration of the DPM synchronization.

備份的必要條件Backup prerequisites

這些是使用 DPM 備份 HYPER-V 虛擬機器的必要條件。These are the prerequisites for backing up Hyper-V virtual machines with DPM.

必要條件Prerequisite 詳細資料Details
DPM 必要條件DPM prerequisites - 如果您想要執行虛擬機器的項目層級復原 (復原檔案、資料夾、磁碟區),則您必須在 DPM 伺服器上安裝 Hyper-V 角色。- If you want to perform item-level recovery for virtual machines (recover files, folders, volumes) then you'll need to install the Hyper-V role on the DPM server. 如果您只想要復原虛擬機器而非項目層級,則角色並非必要條件。If you only want to recover the virtual machine and not item-level then the role isn't required.
- 您可以在一部 DPM 伺服器上保護多達 800 部虛擬機器 (每部 100 GB),並允許可支援較大叢集的多部 DPM 伺服器。- You can protect up to 800 virtual machines of 100 GB each on one DPM server and allows multiple DPM servers that support larger clusters.
- DPM 會將分頁檔從增量備份中排除,以提高虛擬機器備份效能。- DPM excludes the page file from incremental backups to improve virtual machine backup performance.
- DPM 可以備份與 DPM 伺服器在相同網域、子網域或受信任的網域中的 Hyper-V 伺服器或叢集。- DPM can backup a Hyper-V server or cluster in the same domain as the DPM server, or in a child or trusted domain. 如果您想要備份在工作群組或不受信任的網域中的 Hyper-V,您將需要設定驗證。If you want to backup Hyper-V in a workgroup or an untrusted domain you'll need to set up authentication. 對於單一 Hyper-V 伺服器,您可以使用 NTLM 或憑證驗證。For a single Hyper-V server you can use NTLM or certificate authentication. 對於叢集,您只能使用憑證驗證。For a cluster you can use certificate authentication only.
- 不支援在傳遞磁碟上使用主機層級備份來備份虛擬機器資料。- Using host-level backup to back up virtual machine data on passthrough disks isn't supported. 在這種情況下,我們建議您使用主機層級來備份 VHD 檔案,並使用客體層級來備份在主機上看不到的其他檔案。In this scenario we recommend you use host-level back to backup VHD files and guest-level back to back up the other data that isn't visible on the host.
- 使用向外延展 DPM 保護 (多部 DPM 伺服器保護一個大型 Hyper-V 叢集) 來保護 Hyper-V 叢集時,您無法為受保護的 Hyper-V 工作負載新增次要保護。- When protecting a Hyper-V cluster using scaled-out DPM protection (multiple DPM server protecting a large Hyper-V cluster) you can't add secondary protection for the protected Hyper-V workloads.
- 如果 DPM 正在執行 System Center 2012 R2 且 Hyper-V 主機正在 Windows Server 2012 R2 上執行,則您只能備份複本虛擬機器。- You can only backup replica virtual machines if DPM is running System Center 2012 R2 and the Hyper-V host is running on Windows Server 2012 R2.
- 您可以備份重複資料刪除磁碟區。- You can back up deduplicated volumes.
Hyper-V VM 的必要條件Hyper-V VM prerequisites - 在虛擬機器上執行的整合元件版本應該要與執行 Hyper-V 之伺服器上的 Hyper-V 版本相同。- The version of Integration Components that is running on the virtual machine should be the same as the version of Hyper-V on the server that is running Hyper-V.
- 針對每個虛擬機器備份,裝載虛擬硬碟檔案的磁碟區上需有可用空間,以允許 Hyper-V 在備份過程中為差異磁碟 (AVHD) 保留足夠的空間。- For each virtual machine backup you'll need free space on the volume hosting the virtual hard disk files to allow Hyper-V enough room for differencing disks (AVHD's) during backup. 此空間大小必須至少等於計算結果:初始磁碟大小*變換率*備份間隔時間。The space must be at least equal to the calculation Initial disk size*Churn rate*Backup window time. 如果您在叢集上執行多個備份,透過這個計算方式,您需要足夠的儲存容量來容納每個虛擬機器的 AVHD。If you're running multiple backups on a cluster, you'll need enough storage capacity to accommodate the AVHDs for each of the virtual machines using this calculation.
- 如果您想要針對位於執行 Windows Server 2012 R2 之 Hyper-V 主機伺服器上的虛擬機器進行備份,您應該為虛擬機器指定 SCSI 控制器,即使該 SCSI 控制器並未連接到任何項目。- If you want to backup virtual machines located on a Hyper-V host servers running Windows Server 2012 R2, the virtual machine should have a SCSI controller specified, even if it's not connected to anything. 這是因為在 Windows Server 2012 R2 的線上備份中,Hyper-V 主機會在 VM 中裝載新的 VHD,稍後再將它卸載。This is because for online backup in Windows Server 2012 R2 the Hyper-V host mounts a new VHD in the VM and then dismounts it later. 只有 SCSI 控制器可以支援此功能,因此是線上備份虛擬機器的必要條件。Only the SCSI controller can support this and thus is required for online backup of the virtual machine. SCSI 控制器不清除,所以我們才會了解為何需要這個 SCSI 控制器。The SCSI controller doesn't it became clear why we need this SCSI controller. 如果沒有這項設定,當您嘗試備份虛擬機器時,系統將會發出事件識別碼 10103。Without this setting, event ID 10103 will be issued when you try to back up the virtual machine.
Linux 必要條件Linux prerequisites - 您可以使用 DPM 2012 R2 來備份 Linux 虛擬機器。- You can backup Linux virtual machines using DPM 2012 R2. 僅支援檔案一致的快照集。Only file-consistent snapshots are supported.
使用 CSV 儲存空間備份 VMBack up VMs with CSV storage - 若是 CSV 儲存空間,請在 Hyper-V 伺服器上安裝磁碟區陰影複製服務 (VSS) 硬體提供者。- For CSV storage, install the Volume Shadow Copy Services (VSS) hardware provider on the Hyper-V server. 如需 VSS 硬體提供者的資訊,請連絡您的存放區域網路 (SAN) 廠商。Contact your storage area network (SAN) vendor for the VSS hardware provider.
- 如果 CSV 叢集中的單一節點意外關閉,DPM 就會針對該節點上執行的虛擬機器執行一致性檢查。- If a single node shuts down unexpectedly in a CSV cluster, DPM will perform a consistency check against the virtual machines that were running on that node.
- 如果您需要重新啟動已啟用 BitLocker 磁碟區加密的 Hyper-V 伺服器,就必須為 Hyper-V 虛擬機器執行一致性檢查。- If you need to restart a Hyper-V server that has BitLocker Drive Encryption enabled on the CSV cluster, you must run a consistency check for Hyper-V virtual machines.
使用 SMB 儲存空間備份 VMBack up VMs with SMB storage - 在執行 Hyper-V 的伺服器上開啟自動掛接,以啟用虛擬機器保護。- Turn on auto-mount on the server that is running Hyper-V to enable virtual machine protection.
- 停用 TCP Chimney 卸載。- Disable TCP Chimney Offload.
- 確認所有的 Hyper-V machine$ 帳戶對於特定遠端 SMB 檔案共用皆具有完整權限。- Ensure that all Hyper-V machine$ accounts have full permissions on the specific remote SMB file shares.
- 確認復原至替代位置期間,所有虛擬機器元件的檔案路徑長度都不到 260 個字元。- Ensure that the file path for all virtual machine components during recovery to alternate location is less than 260 characters. 若超過以上字元限制,復原可能會成功,但 Hyper-V 將無法掛接虛擬機器。If not, recovery might succeed, but Hyper-V cannot mount the virtual machine.
- 不支援下列案例:- The following scenarios are not supported:
虛擬機器有些元件在本機磁碟區,有些元件在遠端磁碟區的部署;儲存位置檔案伺服器的 IPv4 或 IPv6 位址;以及將虛擬機器復原到使用遠端 SMB 共用的電腦。Deployments where some components of the virtual machine are on local volumes and some components are on remote volumes; an IPv4 or IPv6 address for storage location file server., and recovery of a virtual machine to a computer that uses remote SMB shares.
- 您需要啟用每部 SMB 伺服器的檔案伺服器 VSS 代理程式服務:將它加入 [新增角色及功能] > [選取伺服器角色] > [檔案和存放服務] > [檔案服務] > [檔案服務] > [檔案伺服器 VSS 代理程式服務]。- You'll need to enable the File Server VSS Agent service on each SMB server - Add it in Add roles and features > Select server roles > File and Storage Services > File Services > File Service > File Server VSS Agent Service.

備份虛擬機器Back up virtual machines

  1. 設定您的 DPM 伺服器存放裝置Set up your DPM server and your storage. 設定您的存放裝置時,請使用這些存放裝置容量指導方針。When setting up your storage, use these storage capacity guidelines.

    • 平均虛擬機器大小 - 100 GBAverage virtual machine size - 100 GB
    • 每部 DPM 伺服器的虛擬機器數目 - 800Number of virtual machines per DPM server - 800
    • 800 部 VM 的總大小 - 80 TBTotal size of 800 VMs - 80 TB
    • 備份存放裝置需要的空間 - 80 TBRequired space for backup storage - 80 TB
  2. 設定 Hyper-V 伺服器或 Hyper-V 叢集節點上的 DPM 保護代理程式。Set up the DPM protection agent on the Hyper-V server or Hyper-V cluster nodes. 如果執行客體層級備份,代理程式會安裝在執行客體層級備份的 VM 上。If you're doing guest-level backup you'll install the agent on the VMs you want to back up at the guest-level.

  3. 在 [DPM 系統管理員主控台] 中按一下 [保護] > [建立保護群組],開啟 [建立新保護群組精靈]。In the DPM Administrator console click Protection > Create protection group to open the Create New Protection Group wizard.

  4. 在 [選擇群組成員] 頁面中,從 VM 所在的 Hyper-V 主機伺服器中選取您要保護的 VM。On the Select Group Members page, select the VMs you want to protect from the Hyper-V host servers on which they're located. 建議將擁有相同保護原則的 VM 都放入一個保護群組。We recommend you put all VMs that will have the same protection policy into one protection group. 您可以啟用共置以有效利用空間。To make efficient use of space, enable colocation. 共置可讓您在同一個磁碟或磁帶儲存空間找到不同保護群組的資料,讓多個資料來源只有一個複本和復原點磁碟區。Colocation allows you to locate data from different protection groups on the same disk or tape storage, so that multiple data sources have a single replica and recovery point volume.

  5. 在 [選擇資料保護方式] 頁面上,指定保護群組名稱。On the Select Data Protection Method page, specify a protection group name. 選取 [我想要使用磁碟執行短期保護] ;如果您想要使用 Azure 備份服務將資料備份到 Azure,請選取 [我要執行線上保護] 。Select I want short-term protection using Disk and select I want online protection if you want to back up data to Azure using the Azure Backup service. 如果無法使用此選項,請完成精靈以建立群組,然後修改保護群組設定以選取此選項。If this option isn't available complete the wizard to create the group and then modify the protection group settings to select this option. 您可以在 Azure 中儲存資料長達 3360 天。You can store data in Azure for up to 3360 days.

    如果您有獨立的磁帶或連接至 DPM 伺服器的磁帶媒體櫃,您將能夠選取 [我要使用磁帶執行長期保護]。If you have a standalone tape or tape library connected to the DPM server you'll be able to select I want long-term protection using tape.

  6. 在 [指定短期目標] > [保留範圍]中,指定磁碟資料的保留期限。In Specify Short-Term Goals > Retention range, specify how long you want to retain disk data. 在 [同步處理頻率] 中,指定應執行增量備份資料的頻率。In Synchronization frequency specify how often incremental backups of the data should run. 或者,不要選取增量備份間隔,而是改為啟用 [恰好在復原點之前] 。Alternatively, instead of selecting an interval for incremental backups you can enable Just before a recovery point. 啟用這項設定時,DPM 會在每個排程的復原點之前執行快速完整備份。With this setting enabled DPM will run an express full back just before each scheduled recovery point.

    • 如果您要保護應用程式工作負載,會根據 [同步處理頻率] 建立復原點 (如果應用程式支援增量備份)。If you're protecting application workloads, recovery points are created in accordance with Synchronization frequency, provided the application supports incremental backups. 如果不是,那麼 DPM 將執行快速完整備份而不是增量備份,並根據快速備份排程建立復原點。If it doesn't then DPM runs an express full backup, instead of an incremental backup, and creates recovery points in accordance with the express backup schedule.

    • 如果啟用長期儲存至磁帶,請在 [指定長期目標] > [保留範圍] 中,指定磁帶資料的保留年限 (1-99 年)。If you enable long-term storage to tape, in Specify Long-Term Goals > Retention range, specify how long you want to keep your tape data (1-99 years). 在 [備份頻率] 中選取您想要的備份頻率。In Frequency of backup select the backup frequency that you want.

    • 備份頻率是依指定的保留範圍而定。The backup frequency is based on the specified retention range. 當保留範圍是 1 到 99 年時,您可以選取以下備份頻率:每日、每週、每兩週、每月、每季、每半年或每年。When the retention range is 1-99 years, you can select backups to occur daily, weekly, bi-weekly, monthly, quarterly, half-yearly, or yearly.

    • 當保留範圍是 1 到 11 個月時,您可以選取以下備份頻率:每天、每週、每兩週或每月。When the retention range is 1-11 months, you can select backups to occur daily, weekly, bi-weekly, or monthly. 當保留範圍是 1 到 4 週時,您可以選取以下備份頻率:每日或每週。When the retention range is 1-4 weeks, you can select backups to occur daily or weekly.

    • 在獨立磁帶機上,對於單一保護群組,DPM 會使用相同的磁帶來進行每日備份,直到該磁帶上的空間不足。On a stand-alone tape drive, for a single protection group, DPM uses the same tape for daily backups until there is insufficient space on the tape. 如果啟用共置,資料資源會共置於磁帶上。If you enabled colocation, data resources are colocated on the tape.

    • 如果您設定長期儲存至磁帶,請在 [選取磁帶和媒體櫃詳細資料] 頁面上,指定用於備份此保護群組的磁帶和媒體櫃。If you configured long-term storage to tape, on the Select Tape and Library Details page specify the tape and library that'll be used for back up of this protection group. 您也可以指定是否要壓縮或加密備份資料。You can also specify whether to compress or encrypt the backup data.

  7. 在 [檢閱磁碟配置] 頁面中,檢閱針對此保護群組配置的存放集區磁碟空間。In the Review disk allocation page review the storage pool disk space allocated for the protection group.

    [資料大小總計] 是您想要備份的資料大小,而要佈建在 DPM 上的 [磁碟空間] 是 DPM 建議的保護群組空間。Total Data size is the size of the data you want to back up, and Disk space to be provisioned on DPM is the space that DPM recommends for the protection group. DPM 會根據設定選擇理想的備份磁碟區。DPM chooses the ideal backup volume, based on the settings. 不過,您可以編輯 [磁碟配置詳細資料] 中的備份磁碟區選擇。However, you can edit the backup volume choices in the Disk allocation details. 對於工作負載,請在下拉式功能表中選取慣用的存放裝置。For the workloads, select the preferred storage in the dropdown menu. 您的編輯會變更 [可用的磁碟儲存體] 窗格中的 [儲存體總計] 和 [可用儲存體]。Your edits change the values for Total Storage and Free Storage in the Available Disk Storage pane. 未佈建的空間是 DPM 建議您將加入磁碟區的儲存體數量,之後才能順利繼續備份。Underprovisioned space is the amount of storage DPM suggests you add to the volume, to continue with backups smoothly in the future.

  8. 在 [選擇複本的建立方式] 頁面上,指定如何執行保護群組中資料的初始複寫。On the Choose Replica Creation Method page, specify how the initial replication of data in the protection group will be performed. 如果您選擇要透過網路複寫,我們建議您選擇離峰時間。If you select to replicate over the network we recommended you choose an off-peak time. 若是大量資料或網路狀況不佳,請考慮使用卸除式媒體離線複寫資料。For large amounts of data or less than optimal network conditions, consider replicating the data offline using removable media.

  9. 在 [一致性檢查選項] 頁面上,選取自動執行一致性檢查的方式。On the Consistency Check Options page, select how you want to automate consistency checks. 只有當複本資料變得不一致,或是排程指示時,您才能執行檢查。You can enable a check to run only when replica data becomes inconsistent, or according to a schedule. 如果不想設定自動一致性檢查,您可以滑鼠右鍵按一下保護群組,然後選取 [執行一致性檢查],以手動方式隨時執行檢查。If you don't want to configure automatic consistency checking, you can run a manual check at any time by right-clicking the protection group and selecting Perform Consistency Check.

    建立保護群組後,就會依您選取的方法執行資料的初始複寫。After you create the protection group, initial replication of the data occurs in accordance with the method you selected. 初始複寫後,便會依照保護群組的設定開始每個備份。After initial replication, each backup takes place in line with the protection group settings. 如果您需要復原備份的資料,請注意下列事項:If you need to recover backed up data note the following:

備份針對即時移轉設定的虛擬機器Back up virtual machines configured for live migration

當虛擬機器與即時移轉有關時,只要在 Hyper-V 主機上安裝 DPM 保護代理程式,DPM 就可繼續保護虛擬機器。When virtual machines are involved in live migration, DPM continues to protect the virtual machines as long as the DPM protection agent is installed on the Hyper-V host. DPM 保護虛擬機器的方式取決於所涉及的即時移轉類型。The way in which DPM protects the virtual machines depends on the type of live migration involved.

叢集內的即時移轉:在叢集內移轉虛擬機器時,DPM 會偵測移轉,並從新叢集備份虛擬機器,完全不需要使用者操作。Live migration within a cluster - When a virtual machine is migrated within a cluster DPM detects the migration, and backs up the virtual machine from the new cluster node without any requirement for user intervention. 因為儲存位置未曾變更,所以 DPM 會繼續執行快速完整備份。Because the storage location hasn't changed, DPM continues with express full backups. 在使用兩部 DPM 伺服器保護叢集的調整案例中,無論虛擬機器的移轉位置為何,受 DPM1 保護的虛擬機器仍會繼續受 DPM1 保護。In a scaled scenario with two DPM servers to protect the cluster, a virtual machine that is protected by DPM1 continues to be protected by DPM1, no matter where the virtual machine is migrated.

叢集外的即時移轉:在兩部獨立伺服器、不同的叢集,或是一部獨立伺服器和一個叢集之間移轉虛擬機器時,DPM 會偵測移轉,且不需使用者操作即可備份虛擬機器。Live migration outside the cluster - When a virtual machine is migrated between stand-alone servers, different clusters, or between a stand-alone server and a cluster, DPM detects the migration, and can back up the virtual machine without user intervention.

維持保護的需求Requirements for maintaining protection

在即時移轉期間維持保護的需求如下︰The following are requirements for maintaining protection during live migration:

  • 虛擬機器的 Hyper-V 主機必須位在 VMM 伺服器的 System Center VMM 雲端,且此伺服器至少執行 System Center 2012 SP1。The Hyper-V hosts for the virtual machines must be located in a System Center VMM cloud on a VMM server running at least System Center 2012 with SP1.

  • 所有 Hyper-V 主機都必須安裝 DPM 保護代理程式。The DPM protection agent must be installed on all Hyper-V hosts.

  • DPM 伺服器必須連接至 VMM 伺服器。DPM servers must be connected to the VMM server. VMM 雲端的所有 Hyper-V 主機伺服器也必須連接到 DPM 伺服器。All Hyper-V host servers in the VMM cloud must also be connected to the DPM servers. 這可讓 DPM 與 VMM 伺服器通訊,DPM 就能找出虛擬機器目前正在哪些 Hyper-V 主機伺服器上執行,並從該 Hyper-V 伺服器建立新的備份。This allows DPM to communicate with the VMM server so DPM can find out on which Hyper-V host server the virtual machine is currently running, and to create a new backup from that Hyper-V server. 如果無法建立 Hyper-V 伺服器連線,則備份會失敗,並顯示無法連接到 DPM 保護代理程式的訊息。If a connection can't be established to the Hyper-V server, the back up fails with a message that the DPM protection agent is unreachable.

  • 所有 DPM 伺服器、VMM 伺服器和 Hyper-V 主機伺服器必須位於同一網域。All DPM servers, VMM servers, and Hyper-V host servers must be in the same domain.

即時移轉的詳細資料Details about live migration

於即時移轉期間進行備份時,請注意下列事項︰Note the following for backup during live migration:

  • 即時移轉保護不支援磁帶備份。Live migration protection doesn't support backup to tape.

  • 如果即時移轉會轉移儲存空間,DPM 便會執行虛擬機器的完整一致性檢查,然後繼續執行快速完整備份。If a live migration transfers storage, DPM performs a full consistency check of the virtual machine, and then continues with express full backups. 執行儲存空間的即時移轉時,Hyper-V 會辦識虛擬硬碟 (VHD) 或 VHDX,因而導致 DPM 備份資料大小一次性突然增加。When live migration of storage occurs, Hyper-V reorganizes the virtual hard disk (VHD) or VHDX which causes a one-time spike in the size of the DPM backup data.

  • 在虛擬機器主機上,開啟自動掛接以啟用虛擬保護,並停用 TCP Chimney 卸載。On the virtual machine host, turn on auto-mount to enable virtual protection, and disable TCP Chimney Offload.

  • DPM 會使用連接埠 6070 做為裝載 DPM-VMM 協助程式服務的預設連接埠。DPM uses port 6070 as the default port for hosting the DPM-VMM Helper Service. 若要變更登錄︰To change the registry:

    1. 瀏覽到 HKLM\Software\Microsoft\Microsoft Data Protection Manager\ConfigurationNavigate to HKLM\Software\Microsoft\Microsoft Data Protection Manager\Configuration.
    2. 建立 32 位元 DWORD 值DpmVmmHelperServicePort,然後寫入更新的連接埠號碼以作為登錄機碼的一部分。Create a 32-bit DWORD value: DpmVmmHelperServicePort, and write the updated port number as part of the registry key.
    3. 開啟 <Install directory>\Microsoft System Center 2012\DPM\DPM\VmmHelperService\VmmHelperServiceHost.exe.config,將連接埠號碼從 6070 變更為新的連接埠。Open <Install directory>\Microsoft System Center 2012\DPM\DPM\VmmHelperService\VmmHelperServiceHost.exe.config, and change the port number from 6070 to the new port. 例如:<add baseAddress="net.tcp://localhost:6080/VmmHelperService/" />For example: <add baseAddress="net.tcp://localhost:6080/VmmHelperService/" />
    4. 重新啟動 DPM-VMM 協助程式服務,然後重新啟動 DPM 服務。Restart the DPM-VMM Helper service, and restart the DPM service.

Set up protection for live migrationSet up protection for live migration

若要設定即時移轉的保護:To set up protection for live migration:

  1. 設定 DPM 伺服器與其儲存空間,在VMM 雲端的每部 Hyper-V 主機伺服器或叢集節點上安裝 DPM 保護代理程式。Set up the DPM server and its storage, and install the DPM protection agent on every Hyper-V host server or cluster node in the VMM cloud. 如在叢集中使用 SMB 儲存空間,請在所有叢集節點上安裝 DPM 保護代理程式。If you're using SMB storage in a cluster, install the DPM protection agent on all cluster nodes.

  2. 將 VMM 主控台安裝為 DPM 伺服器的用戶端元件,以便 DPM 能與 VMM 伺服器通訊。Install the VMM console as a client component on the DPM server so that DPM can communicate with the VMM server. 主控台和 VMM 伺服器上執行的主控台應該是相同版本。The console should be the same version as the one running on the VMM server.

  3. 將 DPMMachineName$ 帳戶指派為 VMM 管理伺服器的唯讀系統管理員帳戶。Assign the DPMMachineName$ account as a read-only administrator account on the VMM management server.

  4. 使用 Set-DPMGlobalProperty PowerShell Cmdlet,將所有 HYPER-V 主機伺服器連接到所有 DPM 伺服器。Connect all Hyper-V host servers to all DPM servers with the Set-DPMGlobalProperty PowerShell cmdlet. 此指令程式可接受多個 DPM 伺服器名稱。The cmdlet accepts multiple DPM server names. 請使用此格式:Set-DPMGlobalProperty -dpmservername <dpmservername> -knownvmmservers <vmmservername>Use the format: Set-DPMGlobalProperty -dpmservername <dpmservername> -knownvmmservers <vmmservername>. 如需詳細資訊,請參閱 Set-DPMGlobalPropertyFor more information see Set-DPMGlobalProperty.

  5. 在 VMM 中找到在 VMM 雲端 Hyper-V 上執行的所有虛擬機器後,請設定保護群組,並加入您想要保護的虛擬機器。After all virtual machines running on the Hyper-V hosts in the VMM clouds are discovered in VMM, set up a protection group and add the virtual machines you want to protect. 請注意,在虛擬機器行動性的案例下,您應針對保護群組層級的保護啟用自動一致性檢查。Note that automatic consistency checks should be enabled at the protection group level for protection under virtual machine mobility scenarios.

  6. 設定完成之後,當虛擬機器從某個叢集移轉到另一個叢集時,所有備份都會繼續正常執行。After the settings are configured, when a virtual machine migrates from one cluster to another, all backups continue as expected. 您可以用下列方式確認即時移轉已如預期啟用:You can verify live migration is enabled as expected as follows:

    1. 確認 DPM-VMM 協助程式服務正在執行。Check the DPM-VMM Helper Service is running. 若未執行,請加以啟動。If it isn't start it.

    2. 開啟 Microsoft SQL Server Management Studio,然後連線至裝載 DPM 資料庫 (DPMDB) 的執行個體。Open Microsoft SQL Server Management Studio and connect to the instance that hosts the DPM database (DPMDB). 在 DPMDB 上執行下列查詢:SELECT TOP 1000 [PropertyName] ,[PropertyValue] FROM[DPMDB].[dbo].[tbl_DLS_GlobalSetting]On DPMDB run the following query: SELECT TOP 1000 [PropertyName] ,[PropertyValue] FROM[DPMDB].[dbo].[tbl_DLS_GlobalSetting].

      此查詢包含名為 KnownVMMServer的屬性。This query contains a property, called KnownVMMServer. 這個值應與您透過 Set-DPMGlobalProperty Cmdlet 提供的值相同。This value should be the same value you provided with the Set-DPMGlobalProperty cmdlet.

    3. 執行下列查詢,以針對特定虛擬機器驗證 PhysicalPathXML 中的 VMMIdentifier 參數。Run the following query to validate the VMMIdentifier parameter in the PhysicalPathXML for a particular virtual machine. VMName 替換為虛擬機器名稱。Replace VMName with the name of the virtual machine.

      select cast(PhysicalPath as XML) from tbl_IM_ProtectedObject where DataSourceId in (select datasourceid from tbl_IM_DataSource where DataSourceName like '%<VMName>%')

    4. 開啟此查詢傳回的 .xml 檔,然後驗證 VMMIdentifier 欄位是否具有值。Open the .xml file that this query returns and validate that the VMMIdentifier field has a value.

執行手動移轉Run manual migration

完成上一節中的步驟且 DPM Summary Manager 工作完成後,就會啟用移轉。After you complete the steps in the previous sections, and the DPM Summary Manager job completes, migration is enabled. 根據預設,這項工作會在午夜啟動,並在每天早上執行。By default, this job starts at midnight and runs every morning. 如果您想執行手動移轉以確認一切如預期般運作,請執行下列作業:If you want to run a manual migration, to check everything is working as expected, do the following:

  1. 開啟 SQL Server Management Studio,然後連線至裝載 DPM 資料庫的執行個體。Open SQL Server Management Studio and connect to the instance that hosts the DPM database.

  2. 執行下列查詢: select * from tbl_SCH_ScheduleDefinition where JobDefinitionID='9B30D213-B836-4B9E-97C2-DB03C3EB39D7'Run the following query: select * from tbl_SCH_ScheduleDefinition where JobDefinitionID='9B30D213-B836-4B9E-97C2-DB03C3EB39D7'. 此查詢會傳回 ScheduleIDThis query returns the ScheduleID. 請記下這個識別碼,因為您將在下一個步驟中使用它。Note this ID as you will use it in the next step.

  3. 在 SQL Server Management Studio 中,展開 [SQL Server 代理程式],然後展開 [工作]。In the SQL Server Management Studio, expand SQL Server Agent, and then expand Jobs. 使用滑鼠右鍵按一下您記下的 ScheduleID,然後選取 [從下列步驟啟動作業]。Right-click ScheduleID that you noted, and select Start Job at Step.

請注意,執行此工作時,備份效能會受到影響。Note that backup performance is affected when the job runs. 部署大小與規模將決定完成此工作所需的時間。The size and scale of your deployment determines how much time the job takes to finish.

備份複本虛擬機器Back up replica virtual machines

如果 DPM 正在 Windows Server 2012 R2 或更新版本上執行,您可以在次要伺服器上備份複本虛擬機器。If DPM is running on Windows Server 2012 R2 or greater, then you can back up replica virtual machines on a secondary server. 基於下列幾個理由,這樣做會很有用︰This is useful for several reasons:

減少備份對於執行中工作負載的影響:進行虛擬機器的備份會在建立快照時產生額外負荷。Reduces the impact of backups on the running workload - Taking a backup of a virtual machine incurs some overhead as a snapshot is created. 將備份程序卸載至次要的遠端站台,執行中工作負載就不再受備份作業的影響。By offloading the backup process to a secondary remote site, the running workload is no longer impacted by the backup operation. 這僅適用於備份複本存放在遠端站台上的部署。This is applicable only to deployments where the backup copy is stored on a remote site. 例如,您可以進行每日備份並將資料儲存放在本機,以確保快速還原時間,但從存放在遠端以供長期保存的複本虛擬機器進行每月或每季備份。For example, you might take daily backups and store data locally to ensure quick restore times, but take monthly or quarterly backups from replica virtual machines stored remotely for long-term retention.

節省頻寬:在典型的遠端分公司/總部部署中,您需要適當的已佈建頻寬量,以便在站台間傳輸備份資料。Saves bandwidth - In a typical remote branch office/headquarters deployment you need an appropriate amount of provisioned bandwidth to transfer backup data between sites. 除了資料備份策略,如果您還建立複寫和容錯移轉策略,您可以減少透過網路傳送的冗餘資料量。If you create a replication and failover strategy, in addition to your data backup strategy, you can reduce the amount of redundant data sent over the network. 備份複本虛擬機器資料,而非主要虛擬機器資料,可節省透過網路傳送該備份資料的額外負荷。By backing up the replica virtual machine data rather than the primary, you save the overhead of sending the backed up data over the network.

提供主機服務提供者備份:您可以使用裝載的資料中心做為複本網站,不需要次要資料中心。Enables hoster backup - You can use a hosted datacenter as a replica site, with no need for a secondary datacenter. 在此情況下,主機服務提供者 SLA 需要複本虛擬機器的一致備份。In this case the hoster SLA requires consistent backup of replica virtual machines.

在容錯移轉起始之前,複本虛擬機器會關閉,而 VSS 無法保證複本虛擬機器的應用程式一致備份。A replica virtual machine is turned off until a failover is initiated, and VSS can't guarantee an application-consistent backup for a replica virtual machine. 因此,複本虛擬機器的備份只會處於絕對一致的狀態。Thus the backup of a replica virtual machine will be crash-consistent only. 如果無法保證絕對一致性,備份就會失敗,下列幾種情況可能會發生這個問題:If crash-consistency can't be guaranteed, then the backup will fail and this might occur in a number of conditions:

  • 複本虛擬機器的狀況不良,且情況極為嚴重。The replica virtual machine isn't healthy and is in a critical state.

  • 複本虛擬機器正在重新同步處理 (處於重新同步處理進行中,或需要重新同步處理的狀態)。The replica virtual machine is resynchronizing (in the Resynchronization in Progress or Resynchronization Required state).

  • 主要和次要站台之間虛擬機器的初始複寫正在進行中或擱置中。Initial replication between the primary and secondary site is in progress or pending for the virtual machine.

  • .hrl 記錄檔正套用到複本虛擬機器,或前一個動作會在故障、或已被取消或中斷的虛擬磁碟上套用 .hrl 記錄檔。.hrl logs are being applied to the replica virtual machine, or a previous action to apply the .hrl logs on the virtual disk failed, or was cancelled or interrupted.

  • 複本虛擬機器的移轉或容錯移轉正在進行中Migration or failover of the replica virtual machine is in progress

    • 復原到原始執行個體:當您復原到原始執行個體時,會刪除原始的 VHD。Recover to original instance: When you recover to the original instance, the original VHD is deleted. DPM 會使用 Hyper-V VSS 寫入器,將 VHD 和其他設定檔案復原到原始位置。DPM recovers the VHD and other configuration files to the original location using Hyper-V VSS writer. 在復原程序結束時,虛擬機器仍然具有高度可用性。At the end of the recovery process, virtual machines are still highly available. 資源群組必須存在才能復原。The resource group must be present for recovery. 如果沒有可用的資源群組,請復原至替代位置,然後讓虛擬機器具有高度可用性。If it isn't available, recover to an alternate location and then make the virtual machine highly available.

    • 依虛擬機器復原到任何主機:DPM 支援替代位置復原 (ALR),這樣會將受保護的 Hyper-V 虛擬機器順暢地復原到另一部 Hyper-V 主機,而與處理器架構無關。Recover as virtual machine to any host: DPM supports alternate location recovery (ALR), which provides a seamless recovery of a protected Hyper-V virtual machine to a different Hyper-V host, independent of processor architecture. 復原到叢集節點的 Hyper-V 虛擬機器無法具有高度可用性。Hyper-V virtual machines that are recovered to a cluster node will not be highly available. 如果您選擇此選項,[復原精靈] 會顯示用於識別目的地和目的地路徑的其他畫面。If you choose this option, the Recovery Wizard presents you with an additional screen for identifying the destination and destination path.

    • 複製到網路資料夾:DPM 支援項目層級復原 (ILR),它可讓您進行檔案、資料夾、磁碟區和虛擬硬碟 (VHD) 的項目層級復原,從 Hyper-V 虛擬機器的主機層級備份復原到網路共用或受 DPM 保護之伺服器上的磁碟區。Copy to a network folder: DPM supports item-level recovery (ILR), which allows you to do item-level recovery of files, folders, volumes, and virtual hard disks (VHDs) from a host-level backup of Hyper-V virtual machines to a network share or a volume on a DPM protected server. DPM 保護代理程式不必安裝在客體內,也可執行項目層級復原。The DPM protection agent doesn't have to be installed inside the guest to perform item-level recovery. 如果您選擇此選項,[復原精靈] 會顯示用於識別目的地和目的地路徑的其他畫面。If you choose this option, the Recovery Wizard presents you with an additional screen for identifying the destination and destination path.

  5. 在 [指定復原選項] 中設定復原選項,按一下 [下一步]:In Specify Recovery Options configure the recovery options and click Next:

    • 如果您透過低頻寬復原 VM,請按一下 [修改] 以啟用 [網路頻寬使用節流設定]。If you are recovering a VM over low bandwidth, click Modify to enable Network bandwidth usage throttling. 開啟節流設定選項之後,您可以指定您想要使用的頻寬量和頻寬可用時間。After turning on the throttling option, you can specify the amount of bandwidth you want to make available and the time when that bandwidth is available.
    • 如果您已設定網路,請選取 [使用硬體快照集啟用 SAN 型復原]。Select Enable SAN based recovery using hardware snapshots if you have configured your network.
    • 如果您希望復原程序完成時傳送電子郵件通知,請選取 [此復原完成時傳送電子郵件],然後提供電子郵件地址。Select Send an e-mail when the recovery completes and then provide the email addresses, if you want email notifications sent once the recovery process completes.
