Hi !

Open Nebula uses a sqlite or mysql database, so you should take this into
account in your backup / failover strategy.

If using the mysql backend this could mean using mysqldump in your backup
script, or setting up replication to your secondary frontend node.

I'm not sure what the proper way of backing up sqlite is (maybe the *.backup
* command ?) - but probably by "just" rsyncing you could end up with corrupt
backups.
