Choose what cannot be replaced
List photos, documents and work that exist only on one device. Include files outside the usual folders and note whether cloud files are actually downloaded. Decide how much recent work you can afford to lose.
Keep independent copies
Use local and off-site copies where practical, with version history or offline protection. Sync alone can propagate deletion or corruption; it is not automatically an independent backup. Keep recovery credentials accessible and secure.
Set a schedule you can maintain
Automate supported backup tools where useful, then review failures and storage limits. The appropriate frequency follows how often files change. A universal monthly copy is not enough for everyone's data.
Test restoration
Restore a representative file to a safe separate location and open it. Check documents as well as photos, including any encryption. A completed progress bar and a drive sitting beside the computer do not establish recoverability.
A small restore exercise
Copy one photo and one document back from the backup into a separate test folder. Open both, then check whether an earlier version is available. Avoid restoring over the only working original while learning the process.
Questions about this guide
How can I check whether my backup is actually usable?
Restore a small selection of files to a safe separate location and open them. A completed backup notification does not prove that every file you need can be recovered.
Which files should I prioritise in a home backup?
List irreplaceable photos, documents and records first, including files outside familiar folders. Decide how often those files change and who can access the backup if your main device fails.
