Abstract

A computer-implemented method includes receiving custom metadata for several data items, the data items having system metadata associated therewith, selecting, based on the custom metadata, some of the data items to move between a primary storage system and a secondary storage system, and moving the selected data item(s) between the primary storage system and the secondary storage system. A computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer to cause the computer to perform the foregoing method. A system includes a processor and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to perform the foregoing method.

First claim

What is claimed is:

1 . A computer-implemented method, comprising:
receiving custom metadata for several data items, the data items having system metadata associated therewith; selecting, based on the custom metadata, some of the data items to move between a primary storage system and a secondary storage system; and moving the selected data item(s) between the primary storage system and the secondary storage system.

2 . The computer-implemented method of claim 1 , wherein the selecting includes selecting data items having particular custom metadata for co-location on the secondary storage system.

3 . The computer-implemented method of claim 2 , wherein the selected data items are co-located in a single tape library.

4 . The computer-implemented method of claim 2 , wherein the selected data items are co-located on the same magnetic recording tape.

5 . The computer-implemented method of claim 1 , wherein at least some of the custom metadata is created by deep data inspection techniques.

6 . The computer-implemented method of claim 1 , wherein receiving the custom metadata includes receiving events for the data items; and comprising adding the custom metadata to a database.

7 . The computer-implemented method of claim 6 , wherein some of the data items are selected and moved in response to determining that the custom metadata in the events associated with the some of the data items matches a predefined policy.

8 . The computer-implemented method of claim 1 , wherein the moving is part of a pre-migration process.

9 . The computer-implemented method of claim 1 , wherein the moving is part of a migration process.

10 . The computer-implemented method of claim 1 , wherein the moving is part of recall process.

11 . A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
receive, by the computer, custom metadata for several data items, the data items having system metadata associated therewith; select, by the computer, based on the custom metadata, some of the data items to move between a primary storage system and a secondary storage system; and move, by the computer, the selected data item(s) between the primary storage system and the secondary storage system.

12 . The computer program product of claim 11 , the selecting includes selecting data items having particular custom metadata for co-location on the secondary storage system.

13 . The computer program product of claim 12 , wherein the selected data items are co-located in a single tape library.

14 . The computer program product of claim 12 , wherein the selected data items are co-located on the same magnetic recording tape.

15 . The computer program product of claim 11 , wherein at least some of the custom metadata is created by deep data inspection techniques.

16 . The computer program product of claim 11 , wherein receiving the custom metadata includes receiving events for the data items; and comprising program instructions for causing the computer to add, by the computer, the custom metadata to a database.

17 . The computer program product of claim 16 , wherein some of the data items are selected and moved in response to determining that the custom metadata in the events associated with the some of the data items matches a predefined policy.

18 . The computer program product of claim 11 , wherein the moving is part of a pre-migration process.

19 . The computer program product of claim 11 , wherein the moving is part of a migration process.

20 . A system, comprising:
a processor; and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to: receive custom metadata for several data items, the data items having system metadata associated therewith; select, based on the custom metadata, some of the data items to move between a primary storage system and a secondary storage system; and move the selected data item(s) between the primary storage system and the secondary storage system.
