If you enabled multiple point in time instances when you configured replication for the virtual machine,
vSphere Replication presents the retained instances as standard snapshots after a successful recovery.
You can select one of these snapshots to revert the virtual machine. vSphere Replication does not
preserve the memory state when you revert to a snapshot.
If the recovery fails, the replication of the virtual machines reverts to the replication state before the
attempted recovery. For more information about the failed recovery attempt, check the last recovery error
message in the replication details pane or check vCenter Server tasks.
The recovery might also fail if you use the same name for the virtual machine in a scenario where you
use vSphere Replication to replicate a virtual machine in a single vCenter Server and the vCenter Server
instance has only one host in its inventory. See Error Recovering Virtual Machine in a Single vCenter
Server Instance for more information.
After a successful recovery, vSphere Replication disables the virtual machine for replication if the source
site is still available. When the virtual machine is powered on again it does not send replication data to the
recovery site. To unconfigure the replication, select Stop replication.
When the source virtual machine is no longer in the vCenter Server inventory, the replication is
unconfigured. Unconfigured replications do not appear in the Summary tab nor in the Incoming
Replications or Outgoing Replications tabs. Check vCenter Server task history for information on
performed recoveries.
If a replicated virtual machine is attached to a distributed virtual switch and you attempt to perform a
recovery in an automated DRS cluster, the recovery operation succeeds but the resulting virtual machine
cannot be powered on. Edit the recovered virtual machine settings to attach it to the correct network.
vSphere Replication disconnects virtual machine network adapters to prevent damage in the production
network. After recovery, you must connect the virtual network adapters to the correct network. If target
host or cluster has no access to the DVS the virtual machine was configured with at the source site,
manually connect the virtual machine to a network or other DVS to successfully power on the virtual
machine.
Failback of Virtual Machines in vSphere Replication
Failback of virtual machines between vCenter Server sites is a manual task in vSphere Replication.
Automated failback is not available.
After performing a successful recovery on the target vCenter Server site, you can perform failback. You
log in to the target site and manually configure a new replication in the reverse direction, from the target
site to the source site. The disks on the source site are used as replication seeds, so that
vSphere Replication only synchronizes the changes made to the disk files on the target site. For more
information on replication seeds, see Replicating Virtual Machines Using Replication Seeds.
Before you configure a reverse replication, you must unregister the virtual machine from the inventory on
the source site.
