I plan to reinstall on a cloned VM from the original one, I have cleaned the previous version, and made an engine-setup. So I have backups from the previous Manager, I can backup to the new one. But, reading the overt-engine-backup, it seems to be possible only before doing engine-setup. Is that right or may I launch a backup after an engine-setup ? An engine-clean is enough to use engine-backup ?

Hi I want to reinstall a new clean oVirt Manager, and I have a question : If I install a new manager, do I recover the datacenter and all the Vms installed in it without any lost of data ? What is the best practice to do this safely ? Thank you for your help Alain
Are you planning to install on a new host/VM? You have basically two alternatives: A. backup the DB and restore it on the new engine as described here: http://www.ovirt.org/Ovirt-engine-backup B. Start from scratch with a new engine on a new DB and re-import existing storage domains: http://www.ovirt.org/Features/ImportStorageDomain Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted.
