Recommended procedure following replication failover

Post by drew.green@tjtpa.com »

I've recently established failover replication using Veeam B&R 5.0.1. However, reading through the documentation, it says that the "undo failover" option within Veeam simply reverts the failover VM to the pre-power on state, losing all changes that have been made. That said, what is the best practice to recover from a VM failure when using replication (ie how do I get the changes made to the replica back to the original VM on the original host with minimal downtime)?

The best proceedure would be to remove the original VM, setup a replication for the Now Live VM to replicate back to the production site and then perform a faliover to the replicated VM. Please be very carefull when doing this and ensure that you are most definately running on the failover VM before deleting the original. It would also be advisable to ensure you have a backup of the Now Live VM just incase you need to recover from backup thus containing the latest data.

Anybody please correct me if they feel this is an incorrect method.

p.s It would probably be best to schedule some downtime for this to ensure data integrity, you could also shutdown the failover VM and then copy it back to the production environment and import it old school style.

Thanks for the reply. While Veeam Replication was pretty easy to set up and seems to work pretty well, it appears that the recovery aspect could use some work.

Indeed Drew, I had my reservations but I think I can honestly say this is one of the better products on the market and will only get better as it matures.
