Do you mind if I ask you what your backup regime is? I often ask people when the topic comes up because it's such an important thing. I'm always interested in potentially improving my knowledge and practice.
Firstly I use BTRFS or ZFS for everything that matters. The first stage of backup is filesystem snapshots, that covers the most common restore case of "oops I deleted the wrong file".
Thank you for explaining this to me/us. I have been thinking about what you wrote in the hope that the penny would drop, but no such luck so far... Are you saying that the snapshot _itself_ is literally the first-stage backup?
Next I rsync files to a disk with a BTRFS filesystem and use BTRFS snapshots on that for multiple backups (going back months or years as most files don't change much).
Are the files you rsync to the disk with Btrfs are the snapstop files you mentioned earlier? Or regular files in the "working portion" of the main disk/array/NAS?
Some of those disks with backups are stored offsite.
How do you make this decision, and how is this implemented? Kind regards, Andrew -- OpenPGP key: EB28 0338 28B7 19DA DAB0 B193 D21D 996E 883B E5B9
