I have been testing Duplicati for a couple of months now and absolutely loving it. I am running on canary (220.127.116.11) which I have been finding really stable, and loving the new features.
I have one question however. I started creating backups with “Backup Retention” set to “Keep all backups”. However I have realised that for my needs, and storage capabilities that won’t be feasible, so I have changed the backup configuration to the new “Smart backup retention” policy.
My question is now this - my backup storage (which is being achieved very simply using SFTP to a FreeNAS ZFS volume) hasn’t reduced in size since changing this option, yet I must have dozens of daily backups that can now be pruned from the tree. I’ve tried “Compact Now” but that hasn’t made any difference.
Is there an easy way I can apply the new Smart Retention Policy to an existing backup set? Or is there a way I can manually prune the backup store so that I can get the size down?
