Table Of Contents
Every time that a virtual machine reaches its RPO target, vSphere Replication records approximately 3800
bytes of data in the vCenter Server events database. If you set a low RPO period, this can quickly create a
large volume of data in the database. To avoid creating large volumes of data in the vCenter Server events
database, limit the number of days that vCenter Server retains event data. See Configure Database Retention
Policy in the vCenter Server and Host Management Guide. Alternatively, set a higher RPO value.
NOTE You cannot use the SRM interface to configure replication that uses point in time (PIT) snapshots. To
enable PIT snapshots, configure replication of a virtual machine by using the vSphere Web Client. See
Configure Replication for a Single Virtual Machine in vSphere Replication Administration.
To recover a virtual machine from an older PIT snapshot, you must manually revert the virtual machine to
that snapshot after the recovery. See “Recover a Point-in-Time Snapshot of a Virtual Machine,” on page 46.
vSphere Replication guarantees crash consistency amongst all the disks that belong to a virtual machine. If
you use VSS quiescing, you might obtain a higher level of consistency. The available quiescing types are
determined by the virtual machine's operating system. See Compatibility Matrixes for vSphere Replication
5.5 for Microsoft Volume Shadow Copy Service (VSS) quiescing support for Windows virtual machines.
You can configure virtual machines to replicate to a Virtual SAN datastore on the target site. See Using
vSphere Replication with Virtual SAN in Site Recovery Manager Installation and Configuration for the
limitations when using vSphere Replication with Virtual SAN.
NOTE vSphere 5.5 includes Virtual SAN as an experimental feature. You can perform testing with Virtual
SAN, but it is not supported for use in a production environment. See the release notes for this release for
information about how to enable Virtual SAN.
Prerequisites
Verify that you have deployed and connected vSphere Replication appliances and SRM Server instances at
each site.
Procedure
1 On the vSphere Client Home page, click VMs and Templates.
2 Browse the inventory to find the single virtual machine to replicate using vSphere Replication.
3 Right-click the virtual machine and select vSphere Replication.
4 Use the RPO slider or enter a value to configure the maximum amount of data that can be lost in the
case of a site failure.
The available RPO range is from 15 minutes to 24 hours.
5 Select a Guest OS Quiescing configuration, if applicable to the source virtual machine operating system.
6 If no target file location is specified or to override the default determined by the datastore mappings,
click Browse to select a target location for the virtual machine.
Option Description
Place virtual machine in a datastore
directly
Select a datastore and click OK.
Place virtual machine in a specific
folder in a datastore
Select Specify datastore folder, click Browse to locate the folder, then
double-click the desired folder.
