12 On the Recovery settings page, use the RPO slider or the time spinners to set the acceptable period
for which data can be lost in the case of a site failure.
The available RPO range is from 5 minutes to 24 hours for target and source sites.
13 (Optional) To save multiple replication instances that can be converted to snapshots of the source
virtual machine during recovery, select Enable in the Point in time instances pane, and adjust the
number of instances to keep.
Note You can keep up to 24 instances for a virtual machine. This means that if you configure
vSphere Replication to keep 6 replication instances per day, the maximum number of days you can
set is 4 days.
The number of replication instances that vSphere Replication keeps depends on the configured
retention policy, but also requires that the RPO period is short enough for these instances to be
created. Because vSphere Replication does not check whether the RPO settings will create enough
instances to keep, and does not display a warning message if the instances are not enough, you
must ensure that you set vSphere Replication to create the instances that you want to keep. For
example, if you set vSphere Replication to keep 6 replication instances per day, the RPO period
should not exceed 4 hours, so that vSphere Replication can create 6 instances in 24 hours.
14 Click Next.
15 Choose whether you want to use replication seeds.
This option searches the selected target datastore for replication seeds. If candidate files are found,
confirm whether to use the files as seeds.
16 On the Ready to complete page, review the replication settings, and click Finish.
vSphere Replication starts an initial full synchronization of the virtual machine files to the designated
datastore on the target site.
If a replication source virtual machine is powered off, the replication remains in Not Active state until
you power on the virtual machine.
Move a Replication to a New vSphere Replication Server
After configuring vSphere Replication, you can move replications to other vSphere Replication Server
instances. You might do this to complete maintenance tasks on existing servers or to balance the load on
the servers if one server becomes overloaded with replications.
Prerequisites
Other than the embedded vSphere Replication Server, you must have an additional vSphere Replication
Server deployed and registered.
Procedure
1 Select a replication from Outgoing Replications or Incoming Replications.
2 Right-click a replication and select Move to.
