@stormi Doh. How did I miss that?

Hi, I've just applied the May and two June security updates (total of 8 patches) to a test box, no problems. But before I try these on the live pool: can anyone tell me if a reboot is required? The blog posts referenced do not mention this.

@olivierlambert Merci!

Hi, I'm confused by different versions of documentation for XO, Xenserver etc. and concerned about the recoverability of XO backups of SQL and Exchange server VM's.

1. Does an XO backup with advanced option "normal snapshot" use VSS to provide application consistency? I.e. does it use vm-snapshot-with-quiesce or a normal vm-snapshot?
2. Some sources say the above only works with an additional installation step but it is unclear what that is, the one I found seems to be obsolete per: https://xen-orchestra.com/blog/xenserver-quiesce-snapshots/ If I do vssadmin List Providers the Citrix VSS does NOT appear.
3. https://xen-orchestra.com/docs/backups.html#consistent-backup says that quiesced backups (i.e. quiesced snapshots) are deprecated in favor of RAM-enabled backups. Much slower and larger. Is that the only or the best way to ensure apps can be restored without data corruption?
4. What IS the recommended snapshot method, to ensure backups taken by XO are 100% safe, notably in the case of complex Windows apps like SQL and Exchange?

@julien-f Excellent, thank you!

@normanghenderson Hi Julien, Happy New Year. Just touching base on this? I just made an attempt with xo-server 5.73.0 xo-web 5.76.0 and got the usual SR_OPERATION_NOT_SUPPORTED due to the large disk.

@julien-f Thanks very much. Let me know when there is something to test.

Here's another case in XCP-ng/Xen, which pre/post hooks for XO backups could be used to solve:

Any way to backup VM with USB attached?

There are many situations in which it would be desirable to shut down a VM before backup and start it up again afterwards, especially these cases in which a storage device or USB device needs to be detached or the backup won't run...

Just coming back to this: @olivierlambert
(1) what is the approximate timeframe for VDI.snapshot ?
(2) You said "we have indeed webhooks but for jobs, I wonder it might be trivial to get them for backup" - is that likely to happen soon?
I can't do the code but I can test...

Thanks @olivierlambert. Any thoughts on the pre / post backup scripts idea?
