Sorta contradicts the whole point of deleting a snapshot, no? Or is it
some sort of trash vs (real) delete mechanism?
It's not a Btrfs itself's feature. It's a snapper's feature.
It works as a helper of snapshot management.
1. You takes /snap by "snapper create" command.
2. You delete /snap by "snapper delete" command by mistake.
Then snapper takes a "pre" snapshot just before deleting
/snap.
3. Now /snap is deleted, however, a "pre" snapshot which is
the same as /snap before deleting, is still alive.
I don't know how Btrfs itself undo the deletion of a snapshot.
It works if you manages snapshots not by btrfs directly,
but by snapper.
If I misunderstanding something, sorry for noise.
Thanks,
Satoru
