[Users] Backup and restore procedure?

[Jonathan Daugherty]

Greetings,

I'm working on deploying oVirt for the first time and I need to know
what needs to be backed up in order to be prepared for a system
recovery.  Is this documented?

For the engine, so far I imagine I'd want to back up /etc and dump my
postgres database; the restore procedure for both of those is trivial.
For the nodes, other than /etc, I don't know what needs to be backed
up or what the restore procedure is.  (And backing up /etc just for
this seems a bit ham-fisted.)

What am I missing?

Thanks!
