  • Publication number: 20190278493
    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: 10380072
    Abstract: An information management system can manage the removal of data block entries in a deduplicated data store using working copies of the data block entries residing in a local data store of a secondary storage computing device. The system can use the working copies to identify data blocks for removal. Once the deduplication database is updated with the changes to the working copies (e.g., using a transaction based update scheme), the system can query the deduplication database for the database entries identified for removal. Once identified, the system can remove the database entries identified for pruning and/or the corresponding deduplication data blocks from secondary storage.

  • Publication number: 20190243718
    Abstract: The data storage system according to certain aspects can implement partial file restore, where only a portion of the secondary copy of a file is restored. Such portion may be designated by one or more application offsets for the file. The system may provide an in-chunk index that includes mapping information between the application offsets and the secondary copy offsets. Chunks may refer to logical data units in which secondary copies are stored, and the in-chunk index for a chunk may be stored in secondary storage with the chunk. Because the mapping information may not be provided at a fixed interval, the system can search through application offsets in the in-chunk index to locate the secondary copy offset corresponding to the portion application offset(s). In this manner, the system may restore the designated portion of the secondary copy in a fast and efficient manner by using the in-chunk index.

  • Publication number: 20190227879
    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.

  • Publication number: 20190179713
    Abstract: Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices (e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.
