Abstract

A system for performing storage operations using hierarchically configured storage operation cells. The system includes a first storage manager component and a first storage operation cell. The first storage operation cell has a second storage manager component directed to performing storage operations in the first storage operation cell. Moreover, 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 for performing storage operations using storage operation cells, the system comprising:

a storage manager component executing in one or more computer processors, wherein the storage manager component is configured to instruct alternate storage operations in first and second storage operation cells, wherein the storage manager component maintains an index comprising information received from the first and second storage operation cells about the data copy operations performed by the first and second storage operation cells,

wherein the storage manager component stores information indicative of hierarchical associations between the first storage operation cell and the second storage operation cell, and

wherein the first storage manager component is configured to analyze traffic patterns of the data copy operations in the first and second storage operation cells by consulting information about the data copy operations stored in the index to determine alternate methods of performing data copy operations wherein the first storage manager component directs data copy operations intended for the first storage operation cell to the second storage operation cell.

2. The system of claim 1, wherein the first storage operation cell further comprises a first data agent component for obtaining application-specific data from a client device to be included in one of the data copy operations by the first storage operation cell.

3. The system of claim 2, wherein the first storage manager component directly controls the first data agent component during performance of the one of the data copy operations.

4. The system of claim 2, wherein the first storage manager component instructs the second storage manager component to control the first data agent component during performance of the one of the data copy operations by the first storage operation cell.

5. 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.

6. The system of claim 1, wherein a type of the data copy operation comprises at least one of a snapshot copy, a hierarchical storage management copy and an archive copy.

7. The system of claim 1, wherein the second storage manager component is programmed to instruct a third storage manager component regarding performance of data copy operations in the second storage operation cell.

8. The system of claim 1, wherein the first storage operation cell comprises a higher access criteria than the second storage operation cell.

9. The system of claim 1, wherein the second storage manager component is configured to communicate resource usage information to the first storage manager component.

10. A method for performing storage operations using storage operation cells, the method comprising:

performing alternate storage operations in first and second storage operation cells with a storage manager component executing in one or more computer processors, wherein the storage manager component maintains an index comprising information received from the first and second storage operation cells about the data copy operations performed by the first and second storage operation cells;

storing information indicative of hierarchical associations between the first storage operation cell and the second storage operation cell;

analyzing traffic patterns of the data copy operations in the first and second storage operation cells by consulting information about the data copy operations stored in the index to determine alternate methods of performing data copy operations; and

directing data copy operations intended for the first storage operation cell to the second storage operation cell.

11. The method of claim 10, wherein the first storage operation cell further comprises a first data agent component that obtains application-specific data from a client device to be included in one of the data copy operations by the first storage operation cell.

12. The method of claim 11, wherein the first storage manager component directly controls the first data agent component during performance of the one of the data copy operations.

13. The method of claim 11, wherein the first storage manager component instructs the second storage manager component to control the first data agent component during performance of the one of the data copy operations by the first storage operation cell.

14. The method of claim 10, wherein the first storage manager component comprises a component of a storage operation cell other than the first storage operation cell.

15. The method of claim 10, wherein a type of the data copy operation comprises at least one of a snapshot copy, a hierarchical storage management copy and an archive copy.

16. The method of claim 10, wherein the second storage manager component instructs a third storage manager component regarding performance of data copy operations in the second storage operation cell.

17. The method of claim 10, wherein the first storage operation cell comprises a higher access criteria than the second storage operation cell.

18. The method of claim 10, wherein the second storage manager component is configured to communicate resource usage information to the first storage manager component.
