TrueNAS Scale
ElectricEel-24.10.1
I have a dataset holding daily proxmox backups of my virtual machines and a snapshot task that runs each day on that dataset. Twice a month I’d like to create an archive replication of the latest snapshot to a second TruNAS Scale system. I don’t really care to replicate every daily snapshot, only the one that was created just previous to the archive replication run.
I tried a test run where I tried selecting the snapshot to be replicated using the schedule method, specifying the schedule parameters to be same as used for the snapshot created earlier that day. However when I tried to save the replication config, I got an error saying I needed to specify a naming pattern or regular expression in addition to the schedule (Why?) so I specified a regular expression of “.*”. It’s not at all clear to me if this results in picking ALL snapshots or only the one matching the schedule, especially since the task configuration screen indicates that the regular expression is used to select additional snapshots on top of the one(s) selected by the schedule. I’m also not clear that if specifying the last snapshot implies that all previous snapshots have to be replicated, i.e. the snapshots are incremental and build a chain from the original to the latest.
Anyway, back to my real question: Is there a simple way to say just replicate the state of my data as it was at the time of the last snapshot? Thanks!
