== Backups ==
Yes, backups for the backups are necessary. Specifically, backups of tarsnap ''keys'' are necessary. If you lose the key, you lose your backups. There is no way around this. While saving your key in a password manager, ina text file on your PC, one someone else's PC, or even another server are all possible solutions, it's also good to have an offline copy Just In Case™. We use [ paperbackup] because it's easily read by both machines (QR codes) and humans (plain text). Run your key through this, print the resulting PDF, put it in a folder, put the folder in a box, and put the box somewhere very very safe.
