The system administrator schedules backups of the Identity Appliance single sign-on server on a regular basis.
As a best practice, back up your Identity Appliance, vRealize Appliance, and databases at the same time.
In addition, back up the Identity Appliance in the following cases:
You can use one or more of the following methods to create backups.
The vSphere Export function.
VMware vSphere Data Protection, to create backups of the entire appliance.
vSphere Replication, to replicate the virtual appliance to another site.
VMware Recovery Manager, to enable high availability by backing up the appliance to a different data center.
You can use snapshots for backups only if you store or replicate them to a location other than the appliance location. If the snapshot image is accessible after a failure, using it is the most direct way to recover the appliance.
