[ovirt-users] How to recovery VM's data on SAS disk?Data domain all is local host!

[张余歌]

Dear my friend,recently i deployed ovirt-3.5.6 on my dell server with 
SSD and SAS storage.I was hopeless about disaster recovery until i found
 your github:
https://github.com/chipchaderez/ovirt-disaster-recovery-tool

Enviroment:
1:SSD which i allocate to VM's system disk ,and SAS as VM's data storage disk.
2:i use "allinone"(engine and host on the same server) to deploy ovirt.

Problem:
1:Maybe your github project will be work well in ovirt3.5.6?(because i see your project work on ovirt 3.6)
2:If
 My SSD disk has some deadly error,it's no doubt that it cause broken 
the server And let whole system useless!In this case,what can i do ?I 
was afraid of it for a long time
3:Would you tell me what does the ovirt's engine-backup effect?Will the engine backup help me???

Thanks!
