[pbs-devel] [RFC v2 proxmox-backup 04/21] datastore: ignore trashed snapshots for last successful backup

[Christian Ebner]

Exclude trahed snapshots from looking up the last successful backup
of the group, as trashed items are marked for deletion by the next
garbage collection run and must be considered as if not present
anymore.
