Scott R Dunham: Virtual storage and block level direct access of secondary storage for recovery of backup data. EMC Corporation, Howrey Simon Arnold & White, July 31, 2001: US06269431 (849 worldwide citation)

A data storage system has a primary data storage subsystem including primary data storage and a secondary data storage subsystem including secondary data storage. The secondary data storage contains backup versions of data stored in the primary data storage. To permit a host processor to access a sp ...

Scott R Dunham: Remote control of backup media in a secondary storage subsystem through access to a primary storage subsystem. EMC Corporation, Howrey Simon Arnold & White, March 5, 2002: US06353878 (422 worldwide citation)

A primary data storage subsystem has primary data storage and a storage controller for controlling access of host processors to the primary data storage. The primary data storage subsystem is linked to a secondary data storage subsystem for transfer of backup data between the primary data storage su ...

Percy Tzelnic, Scott R Dunham: Computer data storage physical backup and logical restore. EMC Corporation, Howrey Simon Arnold & White, April 2, 2002: US06366987 (197 worldwide citation)

A data storage system is constructed to rapidly respond to a physical backup request for backup of a physical storage unit such as a disk volume or cylinder. A user, however, may request backup of a logical data structure such as a file having a rather complex mapping to a number of physical storage ...

Philippe Armangau, Scott R Dunham: Computer data storage backup with tape overflow control of disk caching of backup data stream. EMC Corporation, Howrey Simon Arnold & White, April 15, 2003: US06549992 (152 worldwide citation)

A data storage system is constructed to rapidly respond to a backup request by streaming backup data from primary storage to tape. It is desirable to permit the data to be removed from the primary storage at a faster rate than it can be written to tape. The backup data is buffered in a memory buffer ...
