[ovirt-users] Python: Clone snapshot into VM

[gregor]

Hi,

this was also an idea but with the single backup script you have the
advantage of backing up more than one VM at a time to speed up the
overall backup time and therefore to backup to different clusters and
different export domains.

But I will change the tool to set a list of VM's in the configuration to
cover both ways.

greetings
gregor
