VMware Backup Types

During backups of VMware datastores and virtual machines, Replay Manager Service for VMware takes a temporary VMware snapshot.

Backup set options specific to VMware include the following:

  • If the Include virtual machine memory in vSphere snapshot option is selected in the backup set definition, the backup includes the internal state of the virtual machine.
  • If the Create Storage center Replay of Physical RDMs option in selected in the backup set definition, the backup includes the physical mode raw device mappings (pRDMs).
NOTE:Since vSphere cannot create a VMware snapshot of physical RDMs, the physical RDM Replays are unlikely to be consistent with the Replay containing the .vmdk file for the same virtual machine.
NOTE:Windows guest virtual machines that store data for VSS aware applications (like SQL Server or Exchange) on physical RDMs, or iSCSI volumes mapped directly to the guest, may fail to create snapshots when using the VMware Virtual Machines backup extension. This is a known issue with Windows VSS snapshot integration and VMware snapshot creation. If a failure occurs, use the vSphere Client to change the value of the disk.EnableUUID parameter to FALSE.
NOTE:Including virtual machine memory can significantly increase the time it required to create a snapshot and may cause the backup creation to take longer than expected.
