Reversing host-level Hyper-V jobs

Reversing protection allows you to protect your source replica virtual server running on the target back to the original source host.

Make sure you original source virtual machine is not running.
On the Manage Jobs page, highlight the job that you want to reverse and click Reverse in the toolbar. The flow of mirroring and replication data will change. Data will be transmitted from the replica virtual machine on the target back to the original source host.

After the reverse is complete, your source replica virtual machine on the target is being protected to your original source host. In the event you want to go back to your original server roles and hardware configuration, you can failover again.

The original disk structure on the original source virtual machine will be deleted and re-created the first time you perform a reverse. This reverse will perform a full mirror. Subsequent reverses will always perform a file differences mirror.
