摘要： A high availability distributed, deduplicated storage system according to certain embodiments is arranged to include multiple deduplication database media agents. The deduplication database media agents store signatures of data blocks stored in secondary storage. In addition, the deduplication database media agents are configured as failover deduplication database media agents in the event that one of the deduplication database media agents becomes unavailable.

摘要： A system according to certain embodiments associates a signature value corresponding to a data block with one or more data blocks and a reference to the data block to form a signature/data word corresponding to the data block. The system further logically organizes the signature/data words into a plurality of files each comprising at least one signature/data word such that the signature values are embedded in the respective file. The system according to certain embodiments reads a previously stored signature value corresponding to a respective data block for sending from a backup storage system having at least one memory device to a secondary storage system. Based on an indication as to whether the data block is already stored on the secondary storage system, the system reads the data block from the at least one memory device for sending to the secondary storage system if the data block does not exist on the secondary storage system, wherein the signature value and not the data block is read from the at least one memory device if the data block exists on the secondary storage system.

摘要： An information management system according to certain aspects uses backup copies or other secondary copies of production data for the purposes of replicating production data to another client. The secondary copies can be deduplicated copies. By utilizing available secondary copies of the data for replication, the system can reduce the impact on the production machines associated with replication. Utilizing deduplicated copies not only reduces the amount of stored data, but also reduces the amount of data that is communicated between the source and the destination, increasing the speed of the replication process.

摘要： An information management system provides a data deduplication system that uses a primary table, a deduplication chunk table, and a chunk integrity table to ensure that a referenced deduplicated data block is only verified once during the data verification of a backup or other replication operation. The data deduplication system may reduce the computational and storage overhead associated with traditional data verification processes. The primary table, the deduplication chunk table, and the chunk integrity table, all of which are stored in a deduplication database, can also ensure synchronization between the deduplication database and secondary storage devices.
