Sync VMs / Snapshots between Hosts

Post by iwl »

Hi,

I back up my vm to other hosts and hard disks with clone.

I would like to update that clones / copies with the new Snapshoots I've made on some host.

I probably can hack that somehow, but may be there is a solution already.

Is there another tool than the VM GUI for working across hosts may be?

That is not how snapshots are supposed to work, and I suggest that if you need to ask this question then you probably shouldn't be doing it this way. Even with the best will in the world your procedure will be incredibly (and potentially catastrophically) error prone.

I suggest that you avoid snapshots like the plague: apply KISS. Keep one simple VDI in each copy of the VM, and copy that VDI between hosts as needed, completely replacing the older VDI. The first time it will of course be a complete copy of the VM (do not attempt to build the second VM from scratch).

Keep backups too (which snapshots are absolutely not).
