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. The systems and methods 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.
