Abstract: Techniques for recovering a virtual machine are disclosed. In one particular embodiment, the techniques may be realized as a method for recovering a virtual machine comprising the steps of selecting a first backup copy of a virtual machine in a first data store, selecting a second data store; enabling use of the virtual machine by reading from the first data store and writing to the second data store, selecting a second backup copy of the virtual machine, and migrating the virtual machine from the second backup copy to the second data store.

Abstract: A method and apparatus for providing a catalog to optimize stream-based restoration is described. In one embodiment, a method for providing a catalog to optimize stream-based restoration includes processing a catalog that indicates at least one location of at least one data block on backup media, wherein the at least one data block are associated with at least one backup for at least one object and accessing at least one data block using the catalog to create a data stream for restoring the at least one object.

Abstract: A scanning manager scans the file systems of virtual machines running on a base computer. In order to scan a virtual machine, the scanning manager identifies the file on the base machine that represents the virtual machine, freezes the virtual machine, and creates a snapshot thereof. The scanning manager restarts the frozen machine, and starts the snapshot. The files of the snapshot are mapped at a virtual machine level, and the resulting file mapping information is used to scan the files of the virtual machine at a base machine level. The scanning can comprise scanning for malicious code, such as virus signatures. The scanning manager can scan one, multiple or all virtual machine(s) running on the base computer, in conjunction with a full or partial scan of the base computer, or independently.

Abstract: A backup manager backups file systems of virtual machines running on a base computer. In order to backup a virtual machine, the backup manager identifies the file on the base machine that represents the virtual machine, freezes the virtual machine, and creates a snapshot thereof. The backup manager restarts the frozen machine, and starts the snapshot. The files of the file system of the snapshot are mapped at a virtual machine level, and the resulting file mapping information is used to backup the files of the virtual machine at a base machine level. The mapping information is current as of the instant the snapshot was taken. The backup manager can backup one, multiple or all virtual machine(s) running on the base computer, in conjunction with a full or incremental backup of the base computer, or independently.
