[pbs-devel] [PATCH v3 proxmox-backup 10/20] api: tape: check trash marker when trying to write snapshot

[Christian Ebner]

Since snapshots might be marked as trash, the snapshot directory
can still be present until cleaned up by garbage collection.

Therefore, check for the presence of the trash marker after acquiring
the locked snapshot reader and skip over marked ones.
