I have some VMs on XCP-NG with storage on FreeNAS via iSCSI like Tom discuses in several videos. The virtual disks exist in a single dataset that is periodically snapshotted ( is that a word?) in ZFS.
I need to rollback a single VM to its state in a two day old snapshot. What’s the best way to do this? I’ve considered running separate XEN to connect to the backed up copy of the dataset, make a new VM in it and use Clonezilla to copy the image back to the “real” VM. The reason I think I need a new XEN server is because when I tried hooking up a backed up copy of a dataset to the XEN server with the live version, it complained because some IDs were duplicates.
