I pretty much instantly wrote off physical media because I know I won't reliably move it to a separate location. If I'm going to have backups, I want ones that are not within fire/flood range of my computer.
In terms of preventing "oops" moments, I'm mainly relying on software (restic) for that, where I trust that (A) backups always append data rather than replacing and (B) it's logic works for marking which data to purge based on rules is accurate. [0]

- Gigachad 9d agoYou want to make sure the append only is enforced by the hosting provider rather than duplicity. Your backups should be resistant to having an attacker on the system who can run arbitrary commands with duplicity.
- Terr_ 9d agoRight, defense against internal "oops" accidents looks rather different than defense against purposeful sabotage. While the local backup service uses an API-key with limited privileges, I need to go back to the bucket/storage-zone settings and see what I can enable, how it would affect total storage, and whether I (with additional privileges) can reliably grab the correct mix of old-blobs to do a restore.
