[ovirt-users] How to backup/restore the rhevm-VM in hosted-engine ?

[Groten, Ryan]

In my case I actually have a spare server (physical) that I keep patched and up-to-date, the engine backups are automatically transferred there.  If my hosted-engine goes down I restore the engine database on the physical spare and run like that until I can get the hosted-engine back up.

I¡¯ve never tried restoring onto a newly deployed hosted-engine VM using hosted-engine --deploy, but I can¡¯t see why that wouldn¡¯t work (maybe someone else knows if this is possible?).  I¡¯ll give it a try too.

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 ¨Cdeployed 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 ¨Cprf  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?
