I have snapshot replication running between my active and backup NASes. Snapshot Replication is running on a volume that’s ~47TB of data. The backup NAS is basically full (I know) so replication tasks just run until they fail essentially, no new successful snapshots. I cleared off about 4TB from the active NAS, but I believe there’s one snapshot left that is holding that deleted data. When I go to the snapshot list to manually remove it, it gives the error “Failed to delete snapshot, preserved by the system”. I’m assuming it won’t delete this snapshot until there’s a new full snapshot, but I can’t make a new snapshot until I delete this old one. Catch 22 or whatever.
Any ideas? I’d like to not delete this Replication task, since it’ll take so long to replicate a new one, this is live data my company is using for clients. It’s worth noting I am also running Hyperbackup to a third NAS, so I’m not super concerned, but would like to do this as efficiently as possible.
Thanks
