Abstract: A system and method for data deduplication is presented. Data received from one or more computing systems is deduplicated, and the results of the deduplication process stored in a reference table. A representative subset of the reference table is shared among a plurality of systems that utilize the data deduplication repository. This representative subset of the reference table can be used by the computing systems to deduplicate data locally before it is sent to the repository for storage. Likewise, it can be used to allow deduplicated data to be returned from the repository to the computing systems. In some cases, the representative subset can be a proper subset wherein a portion of the referenced table is identified shared among the computing systems to reduce bandwidth requirements for reference-table synchronization.

Abstract: Systems and methods for managing electronic data are disclosed. Various data management operations can be performed based on a metabase formed from metadata. Such metadata can be identified from an index of data interactions generated by a journaling module, and obtained from their associated data objects stored in one or more storage devices. In various embodiments, such processing of the index and storing of the metadata can facilitate, for example, enhanced data management operations, enhanced data identification operations, enhanced storage operations, data classification for organizing and storing the metadata, cataloging of metadata for the stored metadata, and/or user interfaces for managing data. In various embodiments, the metabase can be configured in different ways. For example, the metabase can be stored separately from the data objects so as to allow obtaining of information about the data objects without accessing the data objects or a data structure used by a file system.

Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During restore operations, the system can use the client-side signature repository to identify data blocks located in primary storage. The system can also use the client-side signature repository to identify multiple locations within primary storage where instances of some of the data blocks to be restored are located. Accordingly, during a restore operation of one client computing device, the system can source a data block to be restored to the client computing device from another client computing device that is in primary storage.

Abstract: In accordance with some aspects of the present invention, systems and methods are provided for dynamically and/or automatically selecting and/or modifying data path definitions that are used in performing storage operations on data. Alternate data paths may be specified or selected that use some or all resources that communicate with a particular destination to improve system reliability and performance. The system may also dynamically monitor and choose data path definitions to optimize system performance, conserve storage media and promote balanced load distribution.

Abstract: A system and method for encrypting secondary copies of data is described. In some examples, the system encrypts a secondary copy of data after the secondary copy is created. In some examples, the system looks to information about a data storage system, and determines when and where to encrypt data based on the information.
