Hi friends. Still trying to wrap my head around zfs. I followed SI tutorial and converted my 2 drive BTRFS cache pool to ZFS. . All seems fine and I created a snapshot for all of the datasets. I also created a dataset for each docker folder inside of appdata. Before this process I ran appdata backup plugin that created a zip file once a week of the appdata folder and placed it in a backup share. I then copied the backup share to offsite storage. Fast forward to now.....the appdata backup plugin no longer works for my ZFS dataset so I turned it off. My struggle is understanding how I can move the dataset over to a separate backup location in the event something bad happens to my 2 drive zfs cache pool. In other words how can I backup my datasets and if something does happen, I will be able to restore the latest snapshot to a repaired ZFS cache pool.

 

Thanks for any insight

You can snapshot it then send/receive to a different zfs disk/pool.

I guess that is my problem. How do you copy the snapshots? Command line? Where could I find examples of doing that?

Google zfs send/receive, it's the same as any other OS using zfs.
