Efficiency and limited resources forces me to use this approach. A 
server with access to NetStorage disks that runs several rsync's 
to backup all turned off virtual machine's disks doesn't consume as much 
resources as every single virtual machine turned on and running a rsync 
process on each one would consume.

Best regards.

    While riding in a train between London and Birmingham, a
woman inquired of Oscar Wilde, "You don't mind if I smoke, do
you?"
    Wilde gave her a sidelong glance and replied, "I don't mind
if you burn, madam."
