The whole point of a backup system is to have the ability to restore important files that were lost. An important step in your backup system is to ensure that you can recover the files and that the backup data is not corrupted. There is no point of a backup if you can’t access your data or if the backup itself was corrupt!
This is why it is just as important to do a test restore even if you don’t need to just to make sure your process is working.
Hopefully you have a backup system in place, so go spend some time now to test out that restore process if you haven’t already.
