If you only have one server but a backup of all important data you can use the community applications plugin on your unraid to install the zfs plugin. At boot time if there is a zfs pool detected in the server it gets mounted at /yourZFSpoolname. Then you can use a local rsync or cp command to copy your pool to the unraid drives. For example I use: "rsync -amvhW --no-compress --progress --stats --exclude .DS_Store /pool/ /mnt/user/data" I tested this with a degraded test pool and it worked for me but it could be dangerous and it was not that much faster then a rsync over gigabit ethernet. I am only testing unraid right now and decided for me it is not worth the risk of loosing data and just did the rsync over the network. Because zfs is not officially supported every unraid update can or will break the zfs plugin and you do not have any warning if a drive fails in the zfs pool. I could not even tell that the test pool was degraded when booting the server with only two of the three drives. As long as there is no nativ support for ZFS on Linux build in unraid I will keep a small zfs pool in my microserver as a backup of my important data.
