Abstract
A host server hosting one or more virtual machines can back up host volumes and the one or more virtual machines installed thereon in an application-consistent manner. In one implementation, a host-level requestor instructs a host-level writer to identify which virtual machines qualify for application-consistent backups. The host-level requestor then instructs the host-level writer to initiate virtual machine backups through guest-level requesters in each appropriately-configured virtual machine, wherein the virtual machines create application-consistent backups within the virtual machine volumes. The host-level requester then initiates snapshots of the server volumes on the host-level. The virtual machine-level snapshots can thus be retrieved from within the host-level snapshots of the server volumes.
