Abstract: An information management method and system stores signatures (e.g., hashes or cryptographically unique IDs) corresponding to the individual data blocks of files or other data objects. The method and system may compare signatures for a file against a database of signatures for other stored files. If there are a threshold amount of matching signatures, the system can identify a relationship between the files, such as to identify potential security threats in the information management 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: This application describes techniques for creating a second snapshot of a first snapshot of a set of data, modifying the first snapshot, and reverting the modifications to the first snapshot. For example, portions of one or more transaction logs may be played into a database to put the database in a particular state a particular point in time. The second snapshot may then be used to revert to a prior state of the database such that additional transaction logs may be played into the database. These techniques enable the ability to put the database into multiple states as the database existed at multiple points in time. Therefore, data can be recovered from the database as the data existed at different points in time. Moreover, individual data objects in the database can be accessed and analyzed as the individual data objects existed at different points in time.

Abstract: Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

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 storage operations of a client, the system can generate signatures corresponding to data blocks that are being stored in primary storage. The system can store the generated signatures in the client-side signature repository along with information regarding the location of the corresponding data block within primary storage. As additional instances of the data block are stored in primary storage, the system can store the location of the additional instances in the client-side signature repository.

Abstract: A storage system according to certain embodiments includes a repository of client-side data block signature information representative of a set of data blocks stored in a primary storage subsystem. In some cases, the system sources data blocks for secondary copy and restore operations from the primary storage subsystem instead of the secondary storage subsystem. Where multiple primary storage components (e.g., multiple client computing devices) contain copies of a data blocks involved in a secondary copy or restore operation, the system can decide which client to source the data block from based on sourcing criteria.
