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 l=
ocation. If the hosted-engine needs to be restored for some reason I will =
just recreate the OS and restore the engine database.

Subject: [ovirt-users] How to backup/restore the rhevm-VM in hosted-engine =
?
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 (usi=
ng 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 bu=
t as below:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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=3D1
metadata_feature_version=3D1
timestamp=3D1409743461 (Wed Sep 3 07:24:21 2014)
host-id=3D1

=3D=3D=3D=3D
So are there some proper way to backup the rhevm-vm?
