Abstract: A system and method for efficiently storing data both on-site and off-site in a cloud storage system. Data read and write requests are received by a cloud data storage system. The cloud storage system has at least three data storage layers. A first high-speed layer, a second efficient storage layer, and a third off-site storage layer. The first high-speed layer stores data in raw data blocks. The second efficient storage layer divides data blocks from the first layer into data slices and eliminates duplicate data slices. The third layer stores data slices at an off-site location.

Abstract: Disaster Recovery (DR) and High-Availability (HA) are a critical features required by many information technology systems. DR and HA may be accomplished with a remote secondary site that is kept synchronized with a primary site. To reduce the cost of maintaining a secondary site, the data may be split into two subsets wherein only a first subset of data is kept synchronized at the secondary site using a small bandwidth communication link. The second set of data, which is generally much larger, is periodically backed up at a network accessible back-up location. When a disaster occurs, the secondary site may access the most recent back-up of the second set of data. In a maintenance or limited failure situation, the secondary site can directly access the second data set at the primary site.

Abstract: Data back-ups are a critical task of any information technology department. Data back-ups are typically performed using some type of back-up tape systems. Internet based data storage systems now offer data storage services at low prices. To take advantage of such services, a system and method for efficiently back-up data volumes is disclosed. The data back-up system divides data volumes into fingerprinted data slices. Redundant data slices are then removed. Unique fingerprinted data slices are then copied to an internet based storage provider.
