Backup of Fast Cloned VM
-
Hi,
Before deploying 10's of VM using the fast clone feature for my VDI setup I was asking myself if Xen Orchestra will actually reuse the base disk (only one copy somewhere) and just snapshot the delta disk for each VM.
Will I end up with multiple copies of the base disk for every fast clone VM?

Hi!
It has nothing to do with XO.
XO will make a snapshot on schedule, that will be used as a point of reference.
How the chain is organized in your case depends on XenServer/XCP-ng. Please note that we do a snapshot on the VM itself, so its active disk (the base copy won't contain latest data).

Hello @olivierlambert,
Sorry, I forgot to specify that my question concerned backup of VM not the actual creation. So I'll rephrase.
When you fast-clone a VM and reuse the base disk for multiple VM, do backup of those VMs will all include the same base disk or a single copy of the template base disk will be store once

On the remote side, right? It won't be "dedup" if it's your question
(for now at least).We are thinking on a smart way to dedup it efficiently
It's not trivial because we don't have a lot of control on the host itself, but we might find solutions.
