Recover one file before trusting a backup

A backup becomes useful when you can recover something from it. Test one ordinary file before relying on a reassuring completion message.

Choose a non-sensitive document whose contents you know. Follow your backup service's official restore instructions and recover it to a separate location. Avoid overwriting the working copy during a test. Record which account, device and backup date you used, without putting passwords or recovery codes in the note.

Check the recovered contents

Open the recovered file in a suitable application. Check a recognisable passage, image or sheet, and confirm that this is the version you expected. A filename and plausible file size do not establish that the contents are readable. If the document depends on linked assets, test those too.

Notice what the recovery required: an internet connection, a particular app or access to a second device. Keep the provider's current recovery instructions somewhere you can reach if the main computer fails. Protect that record appropriately.

A successful small test does not prove that every item is backed up or that all future restores will succeed. It does reveal practical gaps while you can still fix them. Repeat after a meaningful change to the backup arrangement, and keep the original working file until the result has been checked.
