As has been pointed out, libvirt provides a means of snapshotting a live
VM's storage, so it is quite possible to backup images from the host
machine. That said, I strongly suggest you consider the following.
While the disk image approach simplifies backup, it complicates
restores. There is no way to restore a few files to the VM, at least not
without restoring the entire image and then manually using guestfs to
extract the needed files. Disk image backups complicate restoring files
to a live VM. My experience is that user errors, inadvertent deletes,
etc., are far more frequent than disaster recovery situations, and so
installing bacula-fd on the VM has worked better for me.
For disaster recovery, I keep a small image file that has OS and
bacula-fd to be used as a "bare metal" boot disk. This can be dd'd to
the VM's disk image so that the VM can be booted, and then a normal
restore can be performed from bconsole on the host, just as would be
done for a real machine.

Hello
I'm going to use Bacula for the first time. I have a virtual server
running on 10 KVM. Is it a problem if I back up all of them with
Bacula? I have Qcow2 disk images. I want to backup these disk images
just like a file.
Is this a problem ?
Thank you in advance for your help.
