A useful backup is one you restore

A backup earns trust only when its files come back. A restore drill proves that the saved data is still usable.

Choose a small but meaningful sample

Pick a folder with documents, photos, and a few nested directories. Restore it to a different location rather than overwriting the original. Check that files open, names survived, and the newest expected edit is present.

Then test one item with context: restore a password database and open it with its application, or restore a project and confirm that its supporting files came with it. This catches assumptions that a checksum alone cannot.

Practice without the original machine

The most important recovery detail is often not in the backup at all. Can you find the encryption key, install the restore tool, and reach the storage account if your main computer is gone? Keep the necessary recovery instructions with your other emergency records.

Make the drill routine

A quarterly sample restore is enough for many personal setups. Record the date, what you restored, and anything that slowed you down. Fix that friction while it is still an exercise.

Keep at least one copy separated from the device and account that make the original data. Automation keeps copies current; separation and restore practice make them useful.
