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. From: Xie, Chao [mailto:[email protected]] Sent: September-05-14 3:23 AM To: Groten, Ryan; [email protected] Subject: 答复: How to backup/restore the rhevm-VM in hosted-engine ? 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? 发件人: Groten, Ryan [mailto:[email protected]] 发送时间: 2014年9月5日 4:29 收件人: Xie, Chao/谢 超; [email protected]<mailto:[email protected]> 主题: RE: How to backup/restore the rhevm-VM in hosted-engine ? 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?
