vSphere Data Protection can be deployed to Virtual Machine File System (VMFS), Network File System (NFS) and Virtual SAN datastores. Management of vSphere Data Protection is done using the vSphere Web Client. vSphere Data Protection is deployed as a virtual appliance with four processors (vCPUs) and at least 4GB of memory depending on the backup data capacity of the appliance. Several backup data capacity configurations are available ranging from .5TB to 8TB per vSphere Data Protection appliance. Capacity requirements are based on the number of protected virtual machines, data quantities, backup data retention periods and data change rates, all of which can vary considerably.
