@starmood For each VM backup run inside of Xen Orchestra it backs up not just the VHD but everything that is needed to restore that VM to any other XCP-ng host. So in a complete loss situation you can load a new XCP-ng Host, setup Xen Orchestra, point the new Xen Orchestra to those backups and restore any of the VM's with all their settings.
The metadata backup of XCP-ng is just that, the metadata of the system and it's not granular. It's good to have because all the things like network setting and what VM's are on the hosts will be there, but the VM backups to me are the most important.
I have a tutorial covering how the backups work, it's from a bit over a year ago and there are EVEN MORE features now and I will be doing a new video this year to cover that.

I also have a tutorial on how you can also automate the backup validation process
