[Users] recommandations for saving backing up ovirt

[Nathanaël Blanchet]

Hi all,

I 'd like to receive any usefull advices from the community about good 
practice of backing up ovirt with the restraint of zero down time.
This involves :

  * saving vms without shutting down (Restoring them can be done with a
    halt). Is live snapshot enough for this? Is lvm or san snapshot
    recommended?
  * saving the postgres database (or only some of main tables). Can we
    do it without stopping engine and the risk of a data corruption? Is
    there a howto?

Thank you for your help.
