Selective data replication system and method

1. A computerized method for copying electronic data stored in a first backup data set, the method comprising:

identifying, in the first backup data set, a data item satisfying a selection criterion based at least in part on a data-specific ID, and wherein the data-specific ID is associated with a software application for the data item or is associated with a file type for the data item; and

copying to a second backup data set at least a portion of the data item, wherein the copying is based on one of at least two differing storage seguence preferences, and wherein the one storage seguence preference is based on the data-specific ID.

2. The method of claim 1 , wherein identifying the data item comprises identifying a full backup within a primary backup data set of application data.

3. The method of claim 1 , wherein identifying the data item comprises identifying a full backup within an auxiliary backup data set of application data.

4. The method of claim 1 , wherein the selection criterion further comprises a time criterion and wherein identifying the data item satisfying the selection criterion comprises comparing a time the data item was stored to the time criterion.

5. The method of claim 4 , wherein the time criterion comprises a day of a week and wherein identifying the data item satisfying the selection criterion comprises comparing a day of the week the data item was stored to the day of the week.

6. The method of claim 4 , wherein the time criterion comprises a day of a month and wherein identifying the data item satisfying the selection criterion comprises comparing a day of the month the data item was stored to the day of the month.

7. The method of claim 1 , wherein the selection criterion further comprises a cycle criterion and wherein identifying the data item satisfying the selection criterion comprises comparing a number of cycles occurring since the data item was stored to the cycle criterion.

8. The method of claim 7 , wherein the cycle criterion comprises a number of full backups performed and wherein identifying the data item satisfying the selection criterion comprises comparing a number of full backups performed since the data item was stored to the number of full backups.

9. The method of claim 1 , comprising indicating that the data item satisfies the selection criteria.

10. The method of claim 9 , wherein indicating that the data item satisfies the selection criterion comprises associating, in a data structure, information with the data item indicating that the data item satisfies the selection criterion.

11. The method of claim 9 , wherein indicating that the data item satisfies the selection criterion comprises associating, in a matrix, information with the data item indicating that the data item satisfies the selection criterion.

12. The method of claim 9 , wherein the data item indicated is de-indicated after the data item is copied to the second backup data set.

13. The method of claim 12 , wherein de-indicating the data item comprises removing, in a data structure, information associated with the data item indicating that the data item satisfies the selection criterion.

14. The method of claim 12 , wherein de-indicating the data item comprises removing, in a matrix, information associated with the data item indicating that the data item satisfies the selection criterion.

15. The method of claim 12 , wherein the data item indicated will not be pruned by a pruning program unless the data item is first de-indicated.

16. The method of claim 1 , wherein the data item comprises a full backup of application data.

17. The method of claim 1 , wherein copying at least a portion of the data item comprises performing an auxiliary copy of at least a portion of the data item.

18. The method of claim 1 , wherein the copying of at least a portion of the data item is a restart-able operation.

19. A system for copying electronic data, the system comprising:

a first backup data set containing one or more data items;

a second backup data set; and

a computer, connectable to the first backup data set and the second backup data set;

wherein the computer is programmed

to identify, in the first backup data set, a first data item satisfying a selection criteria based at least in part on a data-specific ID, wherein the data-specific ID is associated with a software application for the data item or is associated with a file type for the data item; and

to copy at least a portion of the first data item from the first backup data set to the second backup data set, and wherein the copying is based on one of at least two differing storage sequence preferences, and wherein the one storage sequence preference is based on the data-specific ID.

20. A computer usable medium storing program code which, when executed on a computerized device, causes the computerized device to execute a computerized method for copying electronic data stored in a first backup data set, the method comprising:

identifying, in the first backup data set, a data item satisfying a selection criterion based at least in part on a data-specific ID. wherein the data-specific ID is associated with a software application for the data item or is associated with a file type for the data item; and

copying to a second backup data set at least a portion of the data item, and wherein the copying is based on one of at least two differing storage seguence preferences, and wherein the one storage seguence preference is based on the data-specific ID.
