if you unknowingly made a backup of the corrupted file?

Getting complicated. Now you have to keep a folder somewhere with
several old backup files? Not necessary with my password system which
relies only on my wetware, and not some third party's software.

a good backup system does that automatically.

(which is still quite recent),

It might not be that recent. For non-sensitive sites (like iHeart Radio)
I often let the browser remember the password. So I might not need that
password again for several weeks when needed for a new device or
browser. But with my password formula I just pull it out of my head. No
backups needed. Easy peasy.

you might not need *that* password, but the rest of the database will
be accessed on a daily basis, so you will instantly know if it's
corrupted, which is extremely unlikely.
