A backup app’s successful status does not prove that every photograph you need can be restored. Learn the process by restoring one small folder somewhere separate. The aim is to see what comes back without touching your working archive, and to find any gaps while there is time to fix them.

Pick a representative folder

An event folder with originals, edited copies, a video, and a notes file makes a good example. Record the date you intend to restore from. Prepare an inventory you can compare, such as the file count and checksums for a few files.

Restore to a separate location

Choose an empty folder and verify that the source archive will not be overwritten. Make sure you can access the account or backup password safely if required. Save any report that says files were skipped. When the restore completes, compare the folder structure.

Actually open the files

Zoom into an original, open an edited version, and play a video in the middle. If you use an album or catalogue, test whether it can find its linked photos. Record where to restore the catalogue and photos if they need to come back separately.

Record what happened for the next rehearsal

Write down the date, backup version, file count, and any gaps. The time it took helps set expectations for a real restore. If something was missing, adjust the backup scope and repeat the small rehearsal. Set the test output apart from your working copies once it is no longer needed.

Pick a small but demanding sample

An archive may contain more than JPEGs. Choose an original from a family trip, an editing project, a short video and a finished share copy. A folder whose contents belong together makes omissions easier to spot. For example, an editing project might return but fail to find the photograph it references. A simple count would miss that problem. Make a new empty destination for the exercise. Restoring straight into your working archive risks overwriting files that are already there. Open a restored image at full size and play the middle and end of the restored video. If the edit belongs to a catalogue, see whether the project can export a new copy. Include dates, folder order and captions if your work depends on them. A successful exercise shows that you can use several kinds of file after restoring them. Record which samples you tested so you can repeat the same checks after changing the backup.

Repeat the exercise with a lost device in mind

If a computer fails, you may lose a remembered browser login, a password or the key to an external drive. Record which account or device you used to open the backup. Check whether you can reach the necessary recovery information from a different device. Read the backup service's recovery procedure ahead of time. Keep the credentials and recovery information somewhere you can reach independently of the failure you are planning for. At the end, write down how long the restore took and which items were missing. When you know where an omitted file should have come from, fix the backup selection and rehearse again. If you need to estimate the time for the whole archive, record the sample size alongside the time. Connection speed and file count can affect the real result. Run a larger sample when time matters. Include the original examples in the next exercise so you can see whether earlier problems have returned. A short written record makes that next rehearsal much easier to run.
