Top posting Hi, just wrote http://www.ovirt.org/OVirt_Hosted_Engine_Backup_and_Restore and currently testing this. Xie Chao, Groten Ryan: since you already explored this kind of procedure can you help commenting and / or sharing your experience here? Adding infra, since we have Hosted Engine running in oVirt production and they may be interested too. Il 05/09/2014 11:23, Xie, Chao ha scritto:
Hi, Ryan
Thanks for replying. I know your meaning and engine-backup command. But I have some questions with your way: “If the hosted-engine needs to be restored for some reason I will just recreate the OS and restore the engine database”.
Do you recreate the Guest using original host? And the host needn’t to be fresh installed and just excute hosted-engine –deployed again, we can recreate another OS?

In 3.4 there is a backup/restore utility called engine-backup. You can use this to backup the RHEV-M database(s) as well as restore. Of course this won’t backup the Guest OS itself.
My DR strategy is to simply copy off these engine-backup files to another location. If the hosted-engine needs to be restored for some reason I will just recreate the OS and restore the engine database.

Hi,All
As the mauual, I can’t find anyway to backup/restore the rhevm-VM in the hosted-engine. The I just try to backup the storage of rhevm-VM (using cp –prf to make a copy of folder). Then I make some change and replace the origin RHEVM-VM content with my backup folder (of course I shutdown the rhevm-vm first). At last the vm can be up,but the status is *NOT* health but as below:
====================
Status up-to-date : False
Hostname : 193.168.195.248
Host ID : 1
Engine status : unknown stale-data
Score : 2400
Local maintenance : False
Host timestamp : 1409743461
Extra metadata (valid at timestamp):
metadata_parse_version=1
metadata_feature_version=1
timestamp=1409743461 (Wed Sep 3 07:24:21 2014)
host-id=1
score=2400
maintenance=False
state=EngineUp
=============================
So are there some proper way to backup the rhevm-vm?
