the 'best' way to do it is 'from within' the VM

the typical workaround is to mount/fsck a LVM snapshot (don't skip the
fsck, or at least a journal replay)

beyond that, there are a few utilities for specific filesystems:
PartImage [1], dump/restore [2], and i'm sure some others.  I don't
know how would these behave with unclean images, which is what you get
if you pull the image under the VM's feet.

[2] http://dump.sourceforge.net/



So when I boot the VM with for example a live debian system, what would be the best method to backup the complete disk /dev/vda with only the data which is on it over a secure network connection to a destination in the network.
