Abstract

A method for information management comprises monitoring output from an application to an operating system, wherein the output is monitored substantially continuously; determining if a policy applies to data associated with the output; and executing the policy if the policy applies.

Claims

1. A method for information management comprising:

monitoring output from an application to an operating system, wherein the output is monitored substantially continuously;

determining if a policy applies to data associated with the output; and

executing the policy if the policy applies.

2. The method of claim 1, wherein executing the policy includes saving the data.

3. The method of claim 1, wherein executing the policy includes determining whether to store the data in a high performance storage media.

4. The method of claim 1, wherein executing the policy includes updating storage metatdata with information associated with the data.

5. The method of claim 1, wherein executing the policy includes determining whether there is already a copy of the data, and if there is already a copy, then updating copy information and storage location in a storage index.

6. The method of claim 1, wherein executing the policy includes determining whether there is already an old version, and updating version information and storage location in a storage index, if there is already an old version.

7. The method of claim 1, wherein executing the policy includes determining whether a predetermined number of versions has been reached, and deleting the oldest version if the predetermined number has been reached.

8. The method of claim 1, wherein the output is related to deleting the data, and wherein executing the policy includes determining whether the policy allows deletion of the data.

9. The method of claim 1, wherein the output is related to deleting the data, and wherein executing the policy includes updating which version of the data was deleted.

10. The method of claim 1, wherein the output is related to deleting the data, and wherein executing the policy includes maintaining a copy of the data if the policy does not allow deletion of the data.

11. The method of claim 1, wherein the output is related to deleting the data, and wherein executing the policy includes determining whether the policy directs deletion of all copies.

12. The method of claim 1, wherein the output is related to deleting the data, and wherein executing the policy includes determining whether the policy directs deletion of all versions.

13. The method of claim 1, wherein executing the policy includes applying encryption to data if it is confidential data.

14. The method of claim 1, wherein executing the policy includes compressing the data if it is compressible.

15. The method of claim 1, wherein executing the policy includes determining whether the data changes at least at a predetermined frequency, and moving the data to a secondary storage if the data does not change at least at the predetermined frequency.

16. The method of claim 1, wherein executing the policy includes storing the data, and archiving the stored data if a creation date of the stored data is at least as old as a predetermined date.

17. A system for information management comprising:

a processor configured to;

monitor output from an application to an operating system, wherein the output is monitored substantially continuously;

determine if a policy applies to data associated with the output; and

execute the policy if the policy applies; and

a memory coupled to the processor, wherein the memory provides instructions to the processor.

18. The system of claim 17, wherein executing the policy includes saving the data in a remote media.

19. The system of claim i7, wherein executing the policy includes determining whether to store the data in a high performance storage media.

20. A computer program product for information management, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

monitoring output from an application to an operating system, wherein the output is monitored substantially continuously;

determining if a policy applies to data associated with the output; and

executing the policy if the policy applies.
