Recovering Overwritten Business Files Checklist

If a cloud-based document, spreadsheet or presentation has been overwritten, earlier work may still be available through version history. Use this checklist to locate the correct file, preserve recent changes and recover the required content safely.

Step 1 — Stop and Identify the File

• □ Stop unnecessary editing
• □ Confirm the correct filename
• □ Confirm the file owner
• □ Confirm the storage location
• □ Confirm Google Workspace or Microsoft 365
• □ Check whether collaborators are currently editing

Step 2 — Preserve the Current Version

• □ Review the latest content
• □ Identify valid recent changes
• □ Download or copy the current version where appropriate
• □ Notify collaborators
• □ Record what appears to be missing

Step 3 — Open Version History

Google Workspace:

• □ Open the file
• □ Open File → Version history → See version history
• □ Review dates and editor names
• □ Select the likely correct version

Microsoft 365:

• □ Open the file or cloud file listing
• □ Open Version History (filename → Version History, or right-click the file in OneDrive/SharePoint)
• □ Review dates and version numbers
• □ Select the likely correct version

Step 4 — Verify the Earlier Version

• □ Confirm missing content is present
• □ Check formulas
• □ Check links
• □ Check formatting
• □ Check comments
• □ Check attachments
• □ Check dates
• □ Check the correct editor

Step 5 — Choose the Recovery Method

• □ Restore the whole earlier version
• □ Make a separate copy
• □ Download the old version
• □ Copy only the missing content
• □ Ask the file owner to restore it
• □ Escalate to an administrator

Restoring the whole file is faster; recovering only the missing content is often safer.

Step 6 — Check the Result

• □ Reopen the file
• □ Confirm the required work is present
• □ Confirm recent valid work remains
• □ Test formulas
• □ Test links
• □ Check permissions
• □ Inform collaborators

Step 7 — Investigate the Cause

• □ Accidental edit
• □ Incorrect data import
• □ Wrong file opened
• □ Duplicate copies
• □ Excessive edit access
• □ Synchronisation conflict
• □ Former employee account
• □ Suspicious activity
• □ Multiple files affected

Step 8 — Prevent Recurrence

• □ Use one approved cloud copy
• □ Use links rather than attachments
• □ Name important versions
• □ Restrict edit access
• □ Protect key spreadsheet ranges
• □ Review sharing
• □ Store files in approved locations
• □ Confirm backup
• □ Test recovery

Step 9 — Make a Decision

• □ Recovery complete
• □ More versions need checking
• □ Administrator help required
• □ Deleted-file recovery required
• □ Backup restore required
• □ Security investigation required
