[Users] Script to auto backup VMs

Hello, Do you guys know of a script that I could use to backup VMs automatically but creating the lower downtime? I modified a bit the 'virt-backup.pl' script by Daniel Berteaud <daniel(a)firewall-services.com&gt; so it authenticates against Ovirt as shown below: Sys::Virt::CRED_AUTHNAME, Sys::Virt::CRED_PASSPHRASE, However, wondering if I could get advice from you as to which tool or script will do this job better. Thanks --Rizzo
