A social media post by @brankopetric00. "A backup isn't a backup until you have successfully restored from it. Until then, it's just a very expensive file upload called 'Schrödinger's Data'."

Are you sure you have all the files required?

How could I possibly be sure of that? Obviously I've tried my best to backup everything I would ever need. For many reasons I cannot backup every single file so I've made the best decisions around that I know how.

Are they restored with the right permissions and metadata automatically?

Nothing about it is automatic, by design. Doesn't need to be. And permissions aren't something I particularly care about since there aren't multiple users.

I'm backing up and verifying ~ 14 TB of files and have taken great pains to ensure I'm doing everything right.

Any idea why I got downvoted? Also...why the quizzing?

    You check if you backed up everything correctly, and if the process works by restoring the backup and confirming they work.

    But you do you, in the end it's your neck on the line.

    My home files are not business critical infrastructure. I'm taking several steps further than any normie would take. Keeping two backups locally, confirming their byte content, sending a subset of the files to a cloud service.

    To read your comments here it seems you think I'm extremely cavalier and reckless... Because I haven't recopied 14 TB back to their original locations to ensure that... What, copying the files works? Reading the full contents of each file and comparing to the original is somehow lacking? I don't have 14 TB in additional storage lying around to test that... Copying is a still a thing?

    It's not like I lose a billion dollars if I lose some photos. Which again, I've gone to great lengths to keep safe.
