Abstract

A method of restoring data to a selected station from a backup grid, wherein the backup grid is implemented as a network of computer stations serving as peers providing a backup service, the method including, executing an agent on each computer station participating in the backup grid, providing the agent of the selected station with an identifier to find a volume of data previously backed up to the backup grid as a collection of blocks dispersed over the participating stations; locating the blocks belonging to the volume of data; mounting the volume of data as a virtual disk by providing access to the data in the volume wherein the location of the blocks from which the volume of data is made up from is transparent to the accessor.
