Backup VM with hardware passthrough

Gheppy

I have the following scenario :
VM has:

sda where is the OS
sdb where there are data
sdc a HDD on USB passthrough where are backups

I want to back up only to sda, but it gives an error.

Configuration is like this

Your removable device doesn't support to have any snapshot.

By default, when calling VM.snapshot, the XCP-ng API (XAPI) will try to snap every disk of the VM.
Then, XO will only export the disk snapshots without [NOBAK]
Backup is made, then snap remove.

Your issue is in 1. We fixed this via a contribution into XAPI, but it will be only in XCP-ng 8.3. It's already working in XO. See https://xen-orchestra.com/blog/xen-orchestra-5-78/#-vm-snapshot-ignoring-disks for more details.

@olivierlambert
It is home lab but ... (I don't want to lose everything ) it is safe to go for 8.3
Can I do upgrade from command line and not use iso CD

Gheppy

Update to 8.3 with boot CD, all is ok and backup is done with success.
Thank you

This is precisely why we did that feature in Xen API Enjoy!
