Restore from backup
-
Hi,
how exactly should I proceed if I want to restore a VM from backup but not as a new VM, but restore/replace the original one to keep the GUID etc.
Thanks in advance. -
It's a new VM so it get's a new GUID. Why would you want it to have the same one? Also if you keep the snapshot when doing a delta backup you can roll that VM back and keep it's GUID.

Yes I understand that a normal restore will create a new VM. But there are situations where I just need to overwrite the backed up VM itself. So this is only possible with a snapshot and only the new VM is always restored from the backup? -
@abudef
Yes, as far as I know the only way to restore a VM but keep all the GUIDs the same is to roll back a snapshot. -
@lawrencesystems
And what is this option "Use differential restore" for? Do you have experience with it?
-
@abudef
XO will utilize the existing VM disk or snapshot as a base, restoring only the differential data to a new disk saving time. More details are in this blog post
