How do you recover a deleted file or an earlier version?
Efficiency question :
Microsoft 365 lets users recover a deleted file or restore an earlier version of a document stored in SharePoint, OneDrive, or Teams. These features reduce the risk of data loss caused by accidental deletion or unwanted changes.
Key issues:
Recovery depends on the file location, user permissions, and retention settings. Recovering a deleted file must be distinguished from restoring an earlier version.
Challenges:
Deleted files in SharePoint and OneDrive can generally be recovered for 93 days, subject to applicable policies. Earlier versions depend on versioning settings and the limits configured in document libraries.
Technology:
• SharePoint: recycle bin, version history, and library restoration.
• OneDrive: recycle bin, version history, and OneDrive restoration.
• Teams: files in channels are recovered through SharePoint, while files shared in chats are recovered through OneDrive.
• Microsoft Purview: retention policies that preserve certain data according to organizational requirements.
Developer's advice:
Enable and configure versioning in SharePoint libraries. Review retention settings and restrict deletion permissions. Periodically test recovery procedures to confirm that they work.
