Just wondering the above. For example, let’s say you have 2 machines, MachineA and MachineB, that backup path / to the same repo.
Does --group-by="host,paths" group snapshots as:
/
/
So that --prune can then run on groups 1 & 2 separately?
That’s what I’d expect; I’m just trying to confirm it.
I just tried to confirm, it separates as you’d like. --keep-last 1 kept one snapshot “per host” for the same path:
./restic_0.12.0_linux_amd64 -r zz forget --group-by="host,paths" --keep-last 1 --dry-run
enter password for repository:
repository b9c2e8f8 opened successfully, password is correct

Perfect, thanks! I wound up using filtering by specified host instead as I want some hosts to have more snapshots than others.
Note that prune can always only run on the whole repository. The reason is, it must first collect all blobs that are still needed by any of the snapshots and can only then remove the others. But about forget you are right.
Yep, that’s why I switched to just explicitly specifying the hostname instead in each forget command.
