Backblaze B2 is $6TB/mo, so if you have around 300GB... stuff like restic or kopia backups nicely to it

Recently started fiddling with restic and B2, it worked fairly seamlessly once I stopped trying too hard being fancy with permissions and capabilities (cap_dac_read_search). There were some conflicts trying to have both "the way that works interactively" [0] versus "the way that works well with systemd". [AmbientCapabilities=]

One concern I have is B2's downloading costs means verifying remote snapshots could get expensive. I suppose I could use `restic check --read-data-subset X` to do a random spot-check of smaller portions of the data, but I'm not sure how valuable that would be.

I like how it resembles LUKS encryption, where I can have one key for the automated backup process, and a separate memorize-only passphrase for if things go Very Very Wrong.

$72/yr is somewhere around 3x purchase price (per year). BB seems to be pretty smart about managing their exposure, infrastructure overhead, etc.
