marcungeschikts

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

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?

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
