  • Publication number: 20160147472
    Abstract: The systems and methods herein permit storage systems to correctly perform data recovery, such as direct access recovery, of Network Data Management Protocol (“NDMP”) backup data that was modified prior to being stored in secondary storage media, such as tape. For example, as described in greater detail herein, the systems and methods may permit NDMP backup data to be encrypted, compressed, deduplicated, and/or otherwise modified prior to storage. The systems and methods herein also permit a user to perform a precautionary snapshot of the current state of data (e.g., primary data) prior to reverting data to a previous state using point-in-time data.

  • Publication number: 20160004721
    Abstract: Systems and methods are disclosed for block-level incremental replication of a local file system in a source volume/partition to a storage array—replicated to a single logical disk designated by a logical unit number (LUN) with a single volume/partition corresponding to the source. From the perspective of the storage array, non-native data (e.g., data in a local file system residing in locally-attached storage) may be backed up to a LUN that is native to the storage array and thus available for any number of subsequent LUN-based operations. Enhanced data agents, media agents, and storage manager(s), including replication storage policies, operate in concert with the storage array to execute successive file-system-to-LUN block-level replication jobs to protect the data in the local file system.
