Hi,

I re-did the test and it seems that the minimum RPO is one day and if someone could confirm that would be great 

As for the snapshot this time it was synced 

Then I tried to test the fail back and I found that the documentation is not clear :

- it is not clear what is the purpose of the dr-clear playbook 

- it is not clear what does mean : put the target volume in read write mode and source volume in read-only mode

- Do we have to sync back using a new georeplication link from the dr volume to source volume? 

I tried to so, in my first trial I forced the creation of the back georeplication without deleting the content of the source volume then I started the replication manually  (I didn't use the checkpoint) and I stopped the replication once it reached the changelog state, but I couldn't import the source volume I got the error : volume is not empty

In my second trial I deleted and recreated the source volume from scratch and the i started the replication back manually at the end I got the error 

In my third trial I deleted the source volume and recreated it from scratch but I replicated back using the check point method and this time the fail back worked.

 Could someone sheds some light on this? 

Thank you

Regards.

Hi,

Need to understand somethings about DR on oVirt-HI

• What does mean : Scheduling regular backups using geo-replication (point 3.3.4 RHHI 1.7 Doc Maintaining RHHI) :
• Does this mean creating a check-point?
• If yes, does this mean that the geo-replication process will sync data up to that check-point and then stops the synchronization, then repeat the same cycle the day after? does this mean that the minimum RPO is one day?
• I created a snapshot of a VM on the source Manager, I synced the volume then I executed a DR, The VM was started on the Target Manager but the VM didn't have its snapshot, any idea???

Regards, be safe.
