一般移轉效能指引General migration performance guidance

重要

許多 Microsoft SharePoint 和 Microsoft OneDrive 客戶都會對在背景中執行的服務執行業務關鍵應用程式。Many Microsoft SharePoint and Microsoft OneDrive customers run business-critical applications against the service that run in the background. 其中包括內容移轉、資料外洩防護 (DLP) 及備份解決方案。These include content migration, Data Loss Prevention (DLP), and backup solutions. 在這些前所未有的情況中,我們會採取一些步驟來確保 SharePoint 和 OneDrive 服務保持高度可用和可靠的狀態,以便讓在遠端工作情況下比以往更依賴服務的使用者使用。During these unprecedented times, we are taking steps to ensure that SharePoint and OneDrive services remain highly available and reliable for your users who depend on the service more than ever in remote work scenarios.

為了支持這個目標,我們已在平日白天時段內對背景應用程式 (移轉、DLP 和備份解決方案) 上實施更嚴密的節流限制。In support of this objective, we have implemented tighter throttling limits on background apps (migration, DLP and backup solutions) during weekday daytime hours. 在這些情況中,您會認為這些應用程式的輸送量相當有限。You should expect that these apps will achieve very limited throughput during these times. 不過,在夜間和週末時段 內,服務將會準備好處理來自背景應用程式的更大量要求。However, during evening and weekend hours for the region, the service will be ready to process a significantly higher volume of requests from background apps.

Microsoft 可以關閉節流,幫助我進行移轉嗎?Can Microsoft turn off the throttle to help me with migration? 否。No. 節流是為了保護服務的可靠性與可用性。Throttling is in place to protect the reliability and availability of the service. 因此無法停用或暫止節流規則。Throttling rules cannot be disabled or suspended. 開啟支援票證並不會解除節流。Opening a support ticket will not lift throttle. 如需其他資訊,請參閱下方的常見問題集與疑難排解一節。See the FAQ and Troubleshooting section below for additional information.

本主題解說將內容移轉至 Microsoft 365 中的 SharePoint 和 OneDrive 時影響效能的因素。This article explains the factors that influence performance when migrating content to SharePoint and OneDrive in Microsoft 365.

移轉效能可能會受到網路基礎結構、檔案大小、移轉時間和節流的影響。了解這些可協助您規劃並最佳化您的移轉效能。Migration performance can be impacted by network infrastructure, file size, migration time, and throttling. Understanding these will help you plan and maximize the efficiency of your migration.

目前 Microsoft 的 SharePoint 移轉工具 (SPMT) 以及其他第三方廠商工具是使用 SharePoint API 進行移轉。它會利用 Azure 並使用通道來進行大量的內容傳送。無論您使用的是什麼移轉工具,都將會套用這些因素。請按照以下所列的建議來進行每個階段的移轉程序。Currently, Microsoft's SharePoint Migration Tool (SPMT) and other third party vendor tools use the SharePoint API for migration. It leverages Azure and uses channels for large content transfer. Whatever migration tool you use, these factors will apply. Follow the recommendations listed below for each phase of your migration process.

在移轉之前Before migration

計劃對於最佳化移轉至關重要。判斷您需要移轉的內容、安排內容要進行移轉的時間,並決定最佳化移轉基礎結構應該是哪些。Planning is the key to optimizing your migration. Determine what content you need to migrate, prioritize when the content needs to be migrated, and decide on what the optimal migration infrastructure should be.

I. 掃描來源I. Scan the source

正確移轉的第一個規則是了解您的來源;在移轉之前評估及分類內容。哪些內容確實需要移轉?哪些可以不需要移轉?應包含幾個檔案版本?您所移轉的內容量會決定專案的整體大小。The first rule of a good migration is to know your source; evaluate and triage your content before you migrate. What content really needs be migrated? What can be left behind? How many file versions should be included? The amount of content you migrate will determine the overall size of your project.

II. 封裝內容II. Package the content

在此步驟中,利用工具建立要匯入雲端內容的適當套件。在 SPMT 及大部分的協力廠商工具中會自動進行此步驟。This step is where the tool creates a proper package for the content to be imported into the cloud. This step is automated in SPMT and in most third-party tools.

套件大小。 若要改善移轉輸送量,建議您每次傳送至少封裝 250 個檔案。針對傳送大小,建議至少為 100 MB,且每個套件低於 250 MB。遵守這些準則將可更快速上傳至 Azure,並運用移轉 API 的縮放功能。Package size. To improve migration throughput, we recommend that you package at least 250 files per transfer. For the transfer size, we recommend a minimum of 100 MB and less than 250 MB per package. Keeping within these guidelines will result in a faster upload speed to Azure and leverages the scale capabilities of the migration API.

下表根據您要移轉的內容類型,提供您可能會達到的預估的速度類型。The following table provides estimates of the type of speed you may achieve based on the types of content you are migrating.

中繼資料的類型Type of metadata 範例Examples MaximumMaximum
輕量型Light ISO 檔案、視訊檔案ISO files, video files 10 TB/日10 TB/day
Medium 清單項目、Office 檔案 (約 1.5 MB)List items, Office files (~1.5 MB) 1 TB/日1 TB/day
大量Heavy 包含自訂欄、小型檔案的清單項目 (約 50KB)List items with custom columns, small files (~50 kb) 250 GB/日250 GB /day
  • 大型檔案的移轉速度高於較小的檔案。小型檔案可能會造成更大的額外負荷及處理時間,從而直接影響效能。Large file size migrates faster than smaller ones. Small file size can result in larger overhead and processing time which directly impacts the performance.

  • 檔案移轉比物件和清單項目更快速。Files migrate faster than objects and list items.

這個步驟的速度取決於所使用工具的效率及所封裝內容的類型。以智慧的方式分割套件可大幅改善此步驟。此外,請確認已正確設定您用於進行移轉的權限、共用或其他限制,而且在 SharePoint Online 限制與界限內。The speed of this step depends on the efficiency of the tool you are using and the type of content that you package. Splitting your packages in a smart way is something that will greatly improve this step. In addition, ensure that your permissions, sharing, or other limits are set up properly for migration and are within SharePoint limits and boundaries.

注意

如果您打算遷移超過 100 TB,請檢閱下方區段:大型移轉If you are planning to migrate over 100TB, review the following section, Large Migration.

在移轉期間During migration

I. 上傳至 AzureI. Upload to Azure

SPMT 或協力廠商工具會使用移轉 API 將您的內容移轉至 SharePoint,並利用 Azure 作為暫時存放位置。SPMT or your third-party tool will migrate your content into SharePoint using the Migration API, leveraging Azure as a temporary holding place.

如果您的連線狀況良好且可以設定資料中心,請針對 Azure 和 Microsoft 365 帳戶選擇地理位置與您最接近的相同資料中心位置。移轉資料輸送量在離峰時段是最高的,這些時段通常是您所在地區時區的晚上和週末。您所在地區的時區取決於您設定 SharePoint 租用戶的位置。If you have a good connection and can configure your datacenter, choose the same datacenter location closest geographically to you for your Azure and your Microsoft 365 account. Migration data throughput is highest during off-peak hours, which are typically nights and weekends in your region's time zone. Your region's time zone is determined by where your SharePoint tenant is set up.

II. 移轉 APIII. The Migration API

移轉程序的最後一個步驟是將資料從 Azure 移到 SharePoint 時。使用 SPMT 或協力廠商工具時,使用者會感受到這個動作。The final step of the migration process is when the data is moved from Azure to SharePoint. This action is transparent to the user when using SPMT or a third- party tool.

若要改善輸送量,建議使用者盡可能針對不同的網站集合執行平行工作。建議您一次不要送出超過 5,000 個以上的移轉作業/要求。過度佇列網路會建立額外的資料庫負載,並減緩移轉速度。上傳新的移轉要求之前,請確認您的工作已完成。某些工具可能已經為您執行這項作業。To improve throughput, users are encouraged to run parallel tasks against different site collections if possible. We recommend that you do not submit more than 5,000 migration jobs/requests at one time. Over-queuing the network will create an extra load on the database and slow migration down. Make sure your task has completed before you upload a new migration request. Some tools may already be doing this for you.

在移轉期間,您的移轉工作通常會加以節流。實作節流可確保獲得最佳的使用者體驗,以及 SharePoint 的可靠性。它主要用於負載平衡資料庫,且在您的移轉設定錯誤 (例如在單一工作中移轉所有的內容,或嘗試在尖峰時段進行移轉) 時可能會發生。During migration, it is not uncommon for your migration task to be throttled. Throttling is implemented to ensure the best user experience and reliability of SharePoint. It is primarily used to load balance the database and can occur if you misconfigure migration settings, such as migrating all your content in a single task or attempting to migrate during peak hours.

移轉後After migration

移轉完成後,請確認內容已成功移至 SharePoint 或 OneDrive。After the migration is completed, verify that your content has been successfully moved to SharePoint or OneDrive.
