I enabled Delta backups for some VMs, mainly, where I predict I would need file-level restore. The backup is working, I can use functionality to the point, I start to select files to restore, where I can select none, there is a triangle next to the "/" - I figured out, I think that this is due to that some of the servers are set up to use LVM. Is the LVM file level restore not supported or must I set something else?
If this functionality is used and it is very interesting to us, should we switch to a simple layout and ditch LVM?

Here is some tech info:
