I've followed @stefano 's excellent guide https://it-notes.dragas.net/2024/08/21/automating-zfs-snapshots-for-peace-of-mind/ to setup automatic ZFS snapshots on my laptop and servers using zfs-autobackup (https://github.com/psy0rz/zfs_autobackup ).

But there's one thing I'm not quite sure about: if I use zfs-autobackup to make a periodic remote backup from my laptop to my server, what kind of retention scheme would make sense?

Let's say I'd like to make daily backups of my laptop to the server, and keep 7 daily backups for a week, one backup for every month for a year, and keep a yearly backup for 5 years. In zfs-autobackup syntax, it would be "1d1w,1m1y,1y5y" if I'm correct. But the backup server is also automatically snapshotted. So where do I put the retention policy? My gut says something like "1d1w" from the laptop and then "1d1w,1m1y,1y5y" on the backup server should do the trick, but I'm a little bit confused by the double snapshots.

Any words of wisdom are appreciated 😅
