  • Patent number: 11513696
    Abstract: A scalable approach is disclosed for processing auxiliary-copy jobs in a storage management system by using distributed media agent resources instead of a centralized storage manager. Enhanced media agents coordinate and control auxiliary-copy jobs and tap the storage manager to reserve data streams and provide job-specific metadata on demand. An enhanced storage manager may initially select a media agent as “coordinator” to coordinate auxiliary-copy jobs with any number of other media agents, which act as “controllers.” A coordinator media agent is generally responsible for obtaining data stream reservation information from the storage manager and assigning auxiliary-copy jobs to respective controller media agents, based on the components involved in the respective reserved data streams.

  • Patent number: 11175996
    Abstract: According to certain aspects, a method can include receiving an indication that a restoration of a deduplication database using a secondary copy of a file associated with a secondary copy job is complete; retrieving a first data fingerprint from a data storage database, wherein the first data fingerprint is associated with the secondary copy job used to restore the deduplication database; retrieving a second data fingerprint from a deduplication database media agent, wherein the second data fingerprint is associated with the secondary copy job used to restore the deduplication database; comparing the first data fingerprint with the second data fingerprint to determine whether the first data fingerprint and the second data fingerprint match; and transmitting an instruction to the deduplication database media agent to rebuild the restored deduplication database in response to a determination that the first data fingerprint and the second data fingerprint do not match.

  • Publication number: 20210019236
    Abstract: If a deduplication database becomes corrupted or is lost, the deduplication database may be reconstructed by restoring an earlier backup copy of the deduplication database. The backup copy of the deduplication database, however, may not be synced with the deduplicated data blocks that are presently stored in the secondary storage subsystem. To address the possibility of data loss and improve reconstruction timing, a deduplicated storage system is provided according to certain embodiments that uses one or more mechanisms to restore the deduplication database and resync with the secondary storage by using one or more journal files that track the data blocks that have been or may have been deleted from the secondary storage since the last deduplication database backup.
