Azure 備份概觀

為何使用 Azure 備份?Why use Azure Backup?

Azure 備份可提供下列主要優點:Azure Backup delivers these key benefits:

  • 卸載內部部署備份:Azure 備份提供了簡單的解決方案,可讓您將內部部署資源備份到雲端。Offload on-premises backup: Azure Backup offers a simple solution for backing up your on-premises resources to the cloud. 您不需部署複雜的內部部署備份解決方案,即可取得短期與長期備份。Get short and long-term backup without the need to deploy complex on-premises backup solutions.
  • 備份 Azure IaaS VM:Azure 備份提供獨立且隔離的備份,可防止原始資料意外毀損。Back up Azure IaaS VMs: Azure Backup provides independent and isolated backups to guard against accidental destruction of original data. 備份會儲存在復原服務保存庫中,並進行內建的復原點管理。Backups are stored in a Recovery Services vault with built-in management of recovery points. 設定和調整都十分容易,且備份會最佳化,可在必要時輕易還原。Configuration and scalability are simple, backups are optimized, and you can easily restore as needed.
  • 輕鬆調整 - Azure 備份使用 Azure 雲端的基礎功能及無限制調整來提供高可用性,沒有維護或監視的額外負荷。Scale easily - Azure Backup uses the underlying power and unlimited scale of the Azure cloud to deliver high-availability with no maintenance or monitoring overhead.
  • 取得無限制的資料傳輸:Azure 備份不會限制輸入或輸出資料的傳輸,或對傳輸的資料收費。Get unlimited data transfer: Azure Backup doesn't limit the amount of inbound or outbound data you transfer, or charge for the data that's transferred.
    • 輸出資料是指還原作業期間傳輸自復原服務保存庫的資料。Outbound data refers to data transferred from a Recovery Services vault during a restore operation.
    • 如果您使用 Azure 匯入/匯出服務執行離線初始備份以匯出大量資料,則會有輸入資料的相關費用。If you perform an offline initial backup using the Azure Import/Export service to import large amounts of data, there's a cost associated with inbound data. 深入了解Learn more.
  • 確保資料安全性:Azure 備份提供解決方案來保護 傳輸中待用的資料。Keep data secure: Azure Backup provides solutions for securing data in transit and at rest.
  • 集中監視和管理:Azure 備份提供復原服務保存庫中的 內建監視和警示功能Centralized monitoring and management: Azure Backup provides built-in monitoring and alerting capabilities in a Recovery Services vault. 這些功能不需要任何額外的管理基礎結構即可供使用。These capabilities are available without any additional management infrastructure. 您也可以使用 Azure 監視器來擴大監視和報告的規模。You can also increase the scale of your monitoring and reporting by using Azure Monitor.
  • 取得應用程式一致備份:應用程式一致備份表示復原點具有還原備份複本所需的所有資料。Get app-consistent backups: An application-consistent backup means a recovery point has all required data to restore the backup copy. Azure 備份提供應用程式一致備份,確保資料還原不需要其他修正程式。Azure Backup provides application-consistent backups, which ensure additional fixes aren't required to restore the data. 還原應用程式一致的資料會減少還原時間,讓您能夠快速回到執行狀態。Restoring application-consistent data reduces the restoration time, allowing you to quickly return to a running state.
  • 保留短期和長期資料:您可以使用 復原服務保存庫進行短期和長期資料保留。Retain short and long-term data: You can use Recovery Services vaults for short-term and long-term data retention.
  • 自動儲存管理 - 混合式環境通常需要異質性儲存體 - 部份在內部部署,部份在雲端。Automatic storage management - Hybrid environments often require heterogeneous storage - some on-premises and some in the cloud. 使用 Azure 備份,使用內部部署儲存體裝置無需成本。With Azure Backup, there's no cost for using on-premises storage devices. Azure 備份會自動配置和管理備份儲存體,且採用使用時付費制。Azure Backup automatically allocates and manages backup storage, and it uses a pay-as-you-use model. 因此,您只需針對使用的儲存體支付費用。So you only pay for the storage you consume. 深入了解定價。Learn more about pricing.
  • 多個儲存體選項 - Azure 備份提供三種類型的複寫,讓您的儲存體/資料保有高可用性。Multiple storage options - Azure Backup offers three types of replication to keep your storage/data highly available.
    • 本地備援儲存體 (LRS) 會將資料複寫至資料中心的儲存體縮放單位三次 (建立三個資料複本)。Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a storage scale unit in a datacenter. 此資料的所有複本都存在於相同的區域內。All copies of the data exist within the same region. LRS 是保護資料免於本機硬體失敗的低成本選項。LRS is a low-cost option for protecting your data from local hardware failures.
    • 異地備援儲存體 (GRS) 是預設且建議使用的複寫選項。Geo-redundant storage (GRS) is the default and recommended replication option. GRS 會將資料複寫到次要地區 (與來源資料主要位置距離數百英哩)。GRS replicates your data to a secondary region (hundreds of miles away from the primary location of the source data). GRS 的價格高於 LRS,但可為您的資料提供更高層級的持久性,即使遭受區域性中斷也不影響。GRS costs more than LRS, but GRS provides a higher level of durability for your data, even if there's a regional outage.
    • 區域備援儲存體 (ZRS) 會在可用性區域中複寫您的資料,保證相同區域中的資料落地和復原。Zone-redundant storage (ZRS) replicates your data in availability zones, guaranteeing data residency and resiliency in the same region. ZRS 不會停機。ZRS has no downtime. 因此,您需要資料落地且必須沒有停機時間的重要工作負載,可以在 ZRS 中備份。So your critical workloads that require data residency, and must have no downtime, can be backed up in ZRS.
