engine-backup.sh --mode=backup does not check/stop the engine/jboss and does not alert the user.
Should it?
No
I have zero knowledge regarding the way the engine works with the database. Are we completely certain that any "logical transaction" is translated one-to-one to a single database transaction? If so, in principle we can back it up without taking the engine down. IMHO...
I see no reason to force engine down in backup , only in restore when we are stopping the existing database and creating a new clean one , so we have to verify that engine does not lock some objects
Anyway, we should definitely pick up one of the existing relevant wiki pages, update it, and add a link to it from all the others.

Hi,
just a short question:
is this procedure still valid for a full DB-Backup and Restore?
http://www.ovirt.org/Backup_engine_db
I already figured out that it's tailored just for fedora setups, not el6 (systemctl).

Hi Sven, all, In 3.3 there is a new utility called engine-backup. Documentation is currently somewhat lacking. 'engine-backup --help' will tell you its options. As Eli implied below, there is no need to take down the engine/jboss services while backing up. Restore should be done to an empty database. Some improvements for it were merged in recently, some of them will be included in 3.3.1. -- Didi ----- Original Message -----
