1. A system for restoring a backed up virtual machine for execution on a host computing device, based on pre-staging backed up data blocks to a media agent, the system comprising:

  • the host computing device configured to execute the virtual machine based on a recovery point;

    a secondary storage computing device in communication with the host computing device, wherein the secondary storage computing device comprises the media agent, a read-cache, and a shared file system that is configured as the recovery point for the virtual machine;

    a secondary storage device in communication with the secondary storage computing device, wherein the secondary storage device comprises a backup copy of data associated with the virtual machine, wherein the backup copy comprises at least one of a configuration file and a virtual disk;

    a virtualization-client computing device in communication with the secondary storage computing device, wherein the virtualization-client computing device comprises a data agent; and

    wherein the media agent is configured to;

    receive the profile of the virtual machine from the data agent,determine a first set of data blocks to be copied from the backup copy, based on the profile of the virtual machine, andcopy the first set of data blocks from the backup copy to the read-cache; and

    wherein a launch of execution of the virtual machine on the host computing device is based on the first set of data blocks served by the media agent via the recovery point.
