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.
1. A data storage system for reverting data to a previous state using point-in-time data, the system comprising: means for receiving a request from a user to revert data to an earlier state at a previous time using previously obtained point-in-time data;means for presenting the user with an option t
1. A data storage system for reverting data to a previous state using point-in-time data, the system comprising: means for receiving a request from a user to revert data to an earlier state at a previous time using previously obtained point-in-time data;means for presenting the user with an option to take a snapshot of a current state of the data;means for determining whether the user has requested that a snapshot of the current state of the data be taken;means for taking a snapshot of the current state of the data, when the user has requested that a snapshot of the current state of the data be taken; and,means for reverting the data using the previously obtained point-in-time data. 2. The data storage system of claim 1, wherein the means for presenting the user with the option to take the snapshot of the current state of the data includes means for presenting a displayable dialog box that provides the user with: an option to take a snapshot of the current state of the data, and,an option to always take a precautionary snapshot before reverting data. 3. A non-transitory computer-readable storage medium whose contents cause a data storage system to perform operations for reverting a set of data, the operations comprising: performing a precautionary snapshot of a current state of a set of data;reverting the set of data to a previous state using point-in-time data, wherein the precautionary snapshot is performed prior to reverting the set of data;receiving a user request to revert the set of data to a previous state using the point-in-time data;in response to the request, automatically providing a user interface display that presents the user with the option to perform the precautionary snapshot, and,receiving a user selection of the option to perform the precautionary snapshot via the user interface display. 4. The data storage system of claim 1, further comprises: means for presenting a status of pending storage operations in the data storage system. 5. The data storage system of claim 1, wherein the means for presenting the user with the option to take the snapshot is a graphical user interface (GUI). 6. The data storage system of claim 2, wherein the displayable dialog box includes at least one of the following: drop-down menu, check box, or any combination thereof. 7. The data storage system of claim 2, wherein the precautionary snapshot is at least partially based on primary data. 8. The data storage system of claim 2, wherein precautionary snapshot is generated using at least one of the following techniques: copy-on-write, redirect-on-write, split mirror, copy-on-write with background copy, or any combination thereof. 9. The non-transitory computer-readable storage of claim 3, wherein the operations further comprise: prior to performing the precautionary snapshot, taking data for the precautionary snapshot offline. 10. The non-transitory computer-readable storage of claim 3, wherein the operations further comprise: receiving a request to browse previous snapshots and the precautionary snapshot;in response to the request, presenting a graphical user interface (GUI) that includes the previous snapshots and the precautionary snapshot. 11. The non-transitory computer-readable storage of claim 3, wherein the performing the precautionary snapshot of the current state of the set of data further comprises taking a snapshot of data in a primary storage. 12. The non-transitory computer-readable storage of claim 3, wherein the snapshot is of at least one of the following: a file system, an Exchange server, or an SQL database. 13. The non-transitory computer-readable storage of claim 3, wherein the precautionary snapshot is configured to be used for reversible reversion. 14. A method for reverting data to a previous state using point-in-time data, the method comprising: receiving a request from a user to revert data to an earlier state at a previous time using previously obtained point-in-time data;presenting the user with an option to take a snapshot of a current state of the data;determining whether the user has requested that a snapshot of the current state of the data be taken;taking a snapshot of the current state of the data, when the user has requested that a snapshot of the current state of the data be taken; and,reverting the data using the previously obtained point-in-time data. 15. The method of claim 14, wherein the presenting the user with the option to take the snapshot of the current state of the data further comprises: presenting a displayable dialog box that provides the user with: an option to take a snapshot of the current state of the data, and,an option to always take a precautionary snapshot before reverting data. 16. The non-transitory computer-readable storage of claim 15, wherein the operations further comprise: prior to performing the precautionary snapshot, taking data for the precautionary snapshot offline. 17. A method for reverting a set of data, the method comprising: performing a precautionary snapshot of a current state of a set of data;reverting the set of data to a previous state using point-in-time data, wherein the precautionary snapshot is performed prior to reverting the set of data;receiving a user request to revert the set of data to a previous state using the point-in-time data;in response to the request, automatically providing a user interface display that presents the user with the option to perform the precautionary snapshot, and,receiving a user selection of the option to perform the precautionary snapshot via the user interface display. 18. The method of claim 17, wherein the reverting the data using previously obtained point-in-time data further comprises: accessing previously obtained point-in-time data that is stored in a chunk as a modified version of NDMP data; andusing the chunk to revert the data. 19. The method of claim 17, further comprising: prior to performing the precautionary snapshot, taking the data for the precautionary snapshot offline. 20. The method of claim 17, wherein the precautionary snapshot is configured to be used for reversible reversion.
