  • Systems and methods for allocating control of storage media in a network environment
    Patent number: 8291177
    Abstract: A method for dynamically allocating control of a storage device, the method comprising receiving an access request from a first computer requesting access to a storage device; directing, based upon the access request, a first storage controller computer to assume an inactive state with respect to control of the storage device; and directing, based upon the access request, a second storage controller computer to assume an active state with respect to control of the storage device.

  • System and method for performing auxiliary storage operations
    Patent number: 8230195
    Abstract: Systems and methods for protecting data in a tiered storage system are provided. The storage system comprises a management server, a media management component connected to the management server, a plurality of storage media connected to the media management component, and a data source connected to the media management component. Source data is copied from a source to a buffer to produce intermediate data. The intermediate data is copied to both a first and second medium to produce a primary and auxiliary copy, respectively. An auxiliary copy may be made from another auxiliary copy. An auxiliary copy may also be made from a primary copy right before the primary copy is pruned.

  • CLIENT-SIDE REPOSITORY IN A NETWORKED DEDUPLICATED STORAGE SYSTEM
    Publication number: 20120150818
    Abstract: A storage system according to certain embodiments includes a client-side repository (CSR). The CSR may communicate with a client at a higher data transfer rate than the rate used for communication between the client and secondary storage. During copy operations, for instance, some or all of the data being backed up or otherwise copied to secondary storage is stored in the CSR. During restore operations, copies of the data stored in the CSR is accessed from the CSR instead of from secondary storage, improving performance. Remaining data blocks not stored in the CSR can be restored from secondary storage.

  • DISTRIBUTED DEDUPLICATED STORAGE SYSTEM
    Publication number: 20120150826
    Abstract: A distributed, deduplicated storage system according to certain embodiments is arranged in a parallel configuration including multiple deduplication nodes. Deduplicated data is distributed across the deduplication nodes. The deduplication nodes can be networked together and communicate with one another according using a light-weight, customized communication scheme (e.g., a scheme based on FTP or HTTP). In some cases, deduplication management information including deduplication signatures and/or other metadata is stored separately from the deduplicated data in deduplication management nodes, improving performance and scalability.

  • CONTENT ALIGNED BLOCK-BASED DEDUPLICATION
    Publication number: 20120084269
    Abstract: A content alignment system according to certain embodiments aligns a sliding window at the beginning of a data segment. The content alignment system performs a block alignment function on the data within the sliding window. A deduplication block is established if the output of the block alignment function meets a predetermined criteria. At least part of a gap is established if the output of the block alignment function does not meet the predetermined criteria. The predetermined criteria is changed if a threshold number of outputs fail to meet the predetermined criteria.

  • System and method for storing redundant information
    Patent number: 7953706
    Abstract: A method and system for reducing storage requirements and speeding up storage operations by reducing the storage of redundant data includes receiving a request that identifies one or more data objects to which to apply a storage operation. For each data object, the storage system determines if the data object contains data that matches another data object to which the storage operation was previously applied. If the data objects do not match, then the storage system performs the storage operation in a usual manner. However, if the data objects do match, then the storage system may avoid performing the storage operation.
