Thank you for your feedback @stefanflegg !

According to Microsoft you need to use their built in backup feature or a software that supports AD and VSS which will tell the VM OS that it is going to be backed up.
Unless you do this there might be corruption of the AD Databases according to Microsoft.

ALL THO we've been backing up our AD servers with XOA snapshots (Both normal backup and incremental) and had only 1 issue since we started using XOA in 2016.
Since that issue we also use a guest agent (From Ahsay CBS) that makes a Windows System State backup and Windows System Backup.

More info about that can be found here:

Just tried it again...it's all good now!

Even with a sfc and cleanup, manually reinstalling the package caused the same behavior. I've got backups of this system and will build a template from the working backup for if it goes sideways.

I've got other stuff to handle.

@rjt yes exactly.

Can you give some details? How do you imagine to work with that?

Because it might be done via RunX at some point I think 🤔

@olivierlambert : Thank you very much for this information. I really happy with xcp-ng!

Here's how to build it: https://xen-orchestra.com/docs/from_the_sources.html

Great! thanks 🙂

It's fully updated 7.6, so please do all upgrade.

@MajorTom I saw it on my XenOrchestra's and wondered also 🚰

Yes, I know this is not exclusive to C, but there are some facilities to handle this, that are, as far as I know, not available in Node.
