USB sticks are infamously unreliable, not a great backup plan

I realize the wording in my comment was a little ambiguous, but don't worry, that's in addition to my files in general. (Restic, Backblaze B2, memorized passwords/keys, regular integrity checks of remote data.)

After all, even with godlike storage-media on my keychain, it would still be susceptible to a mugger or falling down a deep hole. Until that happens, it provides redundancy and convenience, provided I can bring it to a trustworthy computer.
