Pruning: Way to keep the last N snapshots, regardless of backup frequency

#1

Rather than prune to keep a snapshot for a specific time frame I’d like some way to have it keep the last 3 snapshots (and delete the rest).

That way if a VM is shut down and not backed up I’ll still have the last 3 snapshots in the repository rather than having them age out.

I noticed this issue thread and was wondering if anything came of it (we’re using the linux version to prune due to vertical backup memory limitations).

#2

At this time there isn’t an easy way to specify the number of snapshots to keep regardless of their times. What you can do is to write a script to parse the output of the list command and find out the revisions to deleted and then pass them to the prune command.
