Know what happens when a file is changed or deleted, and keep an independent restorable copy.

The answer in 30 seconds
Cloud storage can make a file available on several devices. Synchronisation may also copy mistakes or deletions across those devices. A backup needs a recovery plan and a restoration test.
Inspect the service's sync, version history and trash settings; keep a separate copy of important files and restore a sample before relying on it as a backup.
Examples to adapt
Check how long the cloud trash and version history retain it; test recovery with a noncritical file.
Confirm you can sign in and retrieve needed documents without that device.
Know whether another editor can delete or replace files for everyone.
Follow the method
- 1Map the files
List important folders and where their originals currently live.
- 2Inspect sync
Learn what a local change or deletion does to the cloud and other devices.
- 3Make a separate copy
Use another destination with access controls and a schedule appropriate to the files.
- 4Test recovery
Restore a few files and check their content, names and versions.
Workshop: prove a copy can be recovered
Choose a harmless test file, change it and check whether the earlier version can be restored. Delete a test copy and inspect the bin and retention period. Finally export a small folder to independent storage.
Sync can spread deletion or an error to every device. Keep a separate copy of essential files and test restoration regularly instead of trusting a green status icon.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Original | Where is the working file? | Locate |
| Sync | What happens on deletion? | Test |
| History | Can an older version be restored? | Check |
| Independent copy | Is it separate from sync? | Keep |
| Recovery | Can you restore without one device? | Practise |
Read the checklist directly in the table.
What to check
A second synced device may mirror the same deletion.
Version history and trash retention vary by service and plan.
Losing the only sign-in method can block recovery.
Common questions
Is a cloud folder a backup?
It may include recovery features, but verify retention, independence and an actual restore before treating it as one.
Should I keep every file online?
Choose based on sensitivity, sharing needs and the service's security and terms.
