The backup datastore stores all the data that is required to recover services according to a Recovery Point Objective (RPO). Determine the target location and make sure that it meets performance requirements.

vSphere Data Protection uses deduplication technology to back up virtual environments at data block level, which enables efficient disk utilization. To optimize backups and leverage the VMware vSphere Storage APIs, all ESXi hosts must have access to the production storage.

Design Implication

SDDC-OPS-BKP-002

Allocate a dedicated NFS datastore for the vSphere Data Protection appliance and the backup data in each region according to Physical Storage Design.

vSphere Data Protection emergency restore operations are possible even when the primary VMware vSAN datastore is not available because the vSphere Data Protection storage volume is separate from the primary vSAN datastore.

The amount of storage required for backups is greater than the amount of storage available in the vSAN datastore.

You must provide an external NFS storage array.
