XO Backup [NOBAK] for full backups

olivierlambert

I don't remember the status about this. I'm adding @marcungeschikts so he can tell us where it is in the backlog, when he's back from holidays

Done in XO Release 5.71 delivered in May, this year.

5.71Release Note

Internal Ref. only NOBAK support for all backup modes with snapshots

@marcungeschikts I understand that this issue has been solved by halting a VM before taking the snapshot. Per this comment by @julien-f , "[...] but we have discussed with the XCP-ng team and they are working on improving this", is there an issue or feature request or ticket to track XCP-ng's work to improve the implementation so that halting a VM is no longer required?

olivierlambert

Not sure to understand. The potential XAPI side improvement is to allow a VM.snapshot command to add extra parameters, excluding some disks.

You don't need to halt a VM to make a snapshot, it's completely unrelated. Maybe I'm missing something?

Hi @bnerickson ,

The xcp-ng part to Exclude VDI from snapshot has been done on XAPI project and can be seen in github https://github.com/xapi-project/xen-api/issues/4551 , but will be only embedded in xcp-ng 8.3 planned around 6 month (+/- 3).

For the XO part, [Backup] Use ignore_vdis param when snapshotting, I will see with the XO Team and Olivier to synchronize the delivery

Commenting as I feel my recent error (https://xcp-ng.org/forum/post/53557) is somehow related to this thread reading through the comments and history.

Does the [NOBAK] need to be in the "Name" or "Description" section? This is not really mentioned anywhere.

Thanks

It is in the official doc: https://xen-orchestra.com/docs/backups.html#exclude-disks

just edit the VM disk name

Found this by googling. Is there any news on being able to exclude disks at the snapshot level?

I have a couple of big SQL server VMs that are too big to snapshot, but the OS disk is relatively small and the attached disks are backed up by a seperate process anyway. So literally just need the OS image backing up.

See https://xcp-ng.org/blog/2022/11/18/xcp-ng-8-3-alpha/#-vm-snapshot-with-disk-exclusion

It's already used/supported by Xen Orchestra. If you want it for production, you'll need to wait for XCP-ng 8.3 to be available
