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.

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 second data copy operation comprises 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 the third storage manager component regarding performance of data copy operations in the second storage operation cell.

8. The system of claim 1, wherein the second and third storage manager components are configured to communicate resource usage information to the first storage manager component.

9. The system of claim 8, wherein the resource usage information comprises a usage of a first storage device of the at least one storage device.

10. A system for performing storage operations using 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 index indicating a location of first data on at least one storage device, and

a second storage manager component directing storage operations performed by the first storage operation cell, wherein the second storage manager component directs performance of a first storage operation on the first data; and

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

a second index indicating a location of 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 component directs performance of a second storage operation on the second data, wherein the second storage operation is different than the first storage operation;

wherein the first storage manager component maintains the manager index comprising information received from the first and second indexes, wherein the manager index further comprises information indicative of 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, wherein the second storage manager component is programmed to instruct the third storage manager component regarding performance of storage operations in the second storage operation cell, and 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.

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

12. A system for performing storage operations using 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 index indicating a location of first data on at least one storage device, and

a second storage manager component directing storage operations performed by the first storage operation cell, wherein the second storage manager component directs performance of a first storage operation on the first data; and

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

a second index indicating a location of 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 component directs performance of a second storage operation on the second data, wherein the second storage operation is different than the first storage operation;

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