Abstract

A system for performing storage operations using hierarchically configured storage operation cells, the system comprising: a first storage manager component; and a first storage operation cell, the first storage operation cell having a second storage manager component directed to performing storage operations in the first storage operation cell; wherein the first storage manager component is programmed to instruct the second storage manager regarding performance of storage operations in the first storage operation cell.

Claims

1. A system that performs storage operations using hierarchically organized storage operation cells, the system comprising:

a first storage manager component in communication with a manager index;

a first storage operation cell comprising;

a first media module that conducts first data between a client component and at least one storage device,

a first index comprising information indicating the location of the first data on the at least one storage device,

a second storage manager component directing storage operations performed by the first storage operation cell wherein the second storage manager directs the performance of a first storage operation of first data in response to instructions received from the first storage manager component, and

wherein the first storage operation cell communicates at least a portion of the information in the first index to the manager index; and

a second storage operation cell hierarchically coupled to the first storage operation cell, the second storage operation cell comprising;

a second media module that conducts second data between a client component and the at least one storage device,

a second index indicating the location of the second data on the at least one storage device, and

a third storage manager component directing storage operations performed by the second storage operation cell wherein the third storage manager directs the performance of a second storage operation of second data in response to instructions received from the second storage manager component,

wherein the second storage operation is different than the first storage operation, and

wherein the second storage operation cell communicates at least a portion of the information in the second index to the manager index,

wherein the first storage manager component instructs the second storage manager component regarding performance of storage operations in the first storage operation cell, wherein the second storage manager component instructs the third storage manager component regarding performance of storage operations in the second storage operation cell,

wherein the first storage manager component maintains the manager index comprising the information received from the first and second indexes, wherein the manager index further comprises information about hierarchical associations between the first storage operation cell and the second storage operation cell, and

wherein the first storage manager component instructs alternate storage operations in the first and second storage operation cells based on the manager index.

2. The system of claim 1, wherein the first storage manager component comprises a component of a storage operation cell other than the first storage operation cell.

3. The system of claim 1, wherein the first storage manager component does not comprise a component of a storage operation cell.

4. The system of claim 1, wherein the first storage operation cell further comprises a first data agent component obtaining application-specific data from the client component.

5. The system of claim 4, wherein the first storage manager component directly controls at least one of the first media module and the first data agent component during performance of storage operations in the first storage operation cell.

6. The system of claim 5, wherein the first storage manager component bypasses the second storage manager component to directly control at least one of the first media module or the first data agent component during performance of storage operations in the first storage operation cell.

7. The system of claim 1, wherein the first storage manager component instructs the second storage manager component regarding a time to perform a storage operation.

8. The system of claim 1, wherein the first storage manager component instructs the second storage manager component regarding a type of storage operation to perform.

9. The system of claim 1, wherein the first storage operation cell is organized according to a functional criteria.

10. The system of claim 9, wherein the functional criteria comprises a type of storage operation performed by the first storage operation cell.

11. The system of claim 1, wherein the first storage operation cell is organized according to a geographic criteria.

12. The system of claim 11, wherein the geographic criteria comprises a physical location of one or more components of the first storage operation cell.

13. The system of claim 1, wherein the second storage manager component communicates status information regarding the first storage operation cell to the first storage manager component.

14. The system of claim 13, wherein the status information comprises information regarding the availability of a component of the first storage operation cell.

15. The system of claim 1, wherein the first storage manager component instructs the third storage manager component regarding performance of storage operations in the second storage operation cell.

16. The system of claim 15, wherein the second storage manager component communicates status information regarding the first storage operation cell to the first storage manager component and the third storage manager component communicates status information regarding the second storage operation cell to the first storage manager component.

17. The system of claim 16, wherein the first storage manager component presents a report of summary information regarding the status information communicated by the first storage operation cell and the status information communicated by the second storage operation cell.

18. The system of claim 15, wherein the second storage manager component instructs the third storage manager component regarding performance of storage operations in the second storage operation cell if a user of the second storage manager component satisfies an access criteria for access to the second storage operation cell.

19. The system of claim 1, wherein the first storage manager component uses the manager index to track logical associations between the first and second media modules and the at least one storage device.

20. The system of claim 1, wherein the first data is associated with a first application and the second data is associated with a second application different from the first application.

21. The system of claim 1, wherein the first storage operation cell comprises a plurality data agent components, wherein each data agent component obtains data from different applications of the client component.

22. The system of claim 1, wherein the second storage manager component instructs the third storage manager component based at least in part on information stored in the first index.

23. The system of claim 1, further comprising a third storage operation cell comprising:

a third media module that conducts third data between the client component and the at least one storage device,

a third index indicating the location of the third data on the at least one storage device, and
