vSphere Data Protection can protect virtual machines that reside on VMware vSAN datastores from host failures. The virtual machine storage policy is not backed up with the virtual machine, but you can restore the storage policy after restoring the virtual machine.

Note

The default vSAN storage policy includes Number Of Failures To Tolerate = 1, which means that virtual machine data is mirrored.

You use vSphere Data Protection to restore virtual machines that fail or whose data must be reverted to a previous state.
