how do you backup your media collection?

so far i used restic and backed it up like the rest of the system (keep 7 daily snapshots, 12 weekly and so on).

now that i have had quite some changes in my media collection with retagging, reripping and other shenanigans, i'm realizing i don't really need to be able to have access to "old" snapshots like the rest of the system.

since the media collection is almost append-only, it would probably make more sense to just keep the last 10 (or other arbitrary number) of snapshots. if i accidentally delete something i can bring it back easily, but i don't need to keep around the various versions of the files.

due to restic's deduplication, i expect that the multiple versions (e.g. with different metadata but generally same content) don't cost too much backup storage, but i still feel like i should handle this differently.

what do you think? boosts welcome :)
