Consider the following scenario:
There is a VM running on Hyper-V at the primary site. The VM is replicated every hour to the DR site.
A routine DR test requires the VM to be failed over to the DR replica for a week, after which it will be failed back to the primary site.
Planned Failover is fairly quick because there is only a maximum of one hour worth of changes to replicate. The problem is that the failback to production which has seven days' worth of changes takes too long to complete. The 'quick rollback' option is already selected.
1. Can the VM which is running from the replica at the DR site can be periodically replicated back to the primary site to reduce the amount of data that has to be transferred at the time of the failback and to protect the data? Essentially reversing the direction of the replication without making the failover permanent.
2. What happens if there is a problem at the DR site while the VM is in a failover state and presumably not protected? Is the only recovery point the original VM at the primary site which could be up to 7 days old?
3. During the lengthy failback operation can you switch on the source (replica) VM while it syncs the disks in an attempt to minimize downtime?
