@iris @maddy @NanoRaptor This isn't an actionable answer, but ideally a backup system should have a way to output a list of pathnames and hashes extracted from the backup, so that you can compare against the live system to prove everything was there in the backup without needing temporary space to actually restore it all.
@dalias @iris @maddy @NanoRaptor It should. But that only proves that it can restore the files that are actually in it. Maybe a misconfigured exception rule was catching files it shouldn't. Or you have dependencies: like your password safe with the backup password is inside the backup. There are many things that can go wrong. Simulating a DR situation, actually restoring and testing whether you can continue working is a good practice.
