10. The method of claim 1, comprising indicating that the data item satisfies the selection criteria.
11. The method of claim 10, 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.
12. The method of claim 10, 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.
13. The method of claim 10, wherein the data item indicated is de-indicated after the data item is copied to the second backup data set.
14. The method of claim 13, 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.
15. The method of claim 13, 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.
16. The method of claim 13, wherein the data item indicated will not be pruned by a pruning program unless the data item is first de-indicated.
17. The method of claim 1, wherein the data item comprises a full backup of application data.
18. 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.
19. The method of claim 1, wherein the copying of at least a portion of the data item is a restart-able operation.
20. 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; and to copy at least a portion of the first data item from the first backup data set to the second backup data set.
21. 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; and
copying to a second backup data set at least a portion of the data item.
