When you perform failover, the state of the original VM on the source host is not affected in any way. If you need to test the VM replica and its restore points for recoverability, you can perform failover while the original VM is running. You can also undo failover and get back to the normal mode of operation.
In a case of permanent failover
, the VM replica ceases to exist as a replica and takes on the role of the original VM.
VBR removes the VM replica from list of replicas, reconfigures the replication job and adds the original VM to the list of exclusions. When the replication job starts, the original VM is skipped from processing. As a result, no data is written to the working VM replica. Thanks!
