Abstract
A method, system, computer system, and computer-readable medium that enable a secondary host that is not the file system host to create a backup of a clone file set that shares at least one data block on a storage device with an active file set. Start and end locations are identified for a set of contiguous storage locations (referred to as a 'chunk') on the storage device. Physical location information is obtained for each portion of a file contained in the chunk. The start and end locations and physical location information for portions of files contained in the chunk are provided to the secondary host, which sequentially reads data from the set of contiguous storage locations and constructs a copy of the file(s) making up the clone file set. The file(s) are written by the secondary host to a storage device to create a backup of the clone file set.
