Abstract

Multi-dimensional surrogation systems and methods are provided that generate at least one data surrogate using information of data and numerous data changes received from at least one data source. The multi-dimensional surrogation transforms data of each data surrogate from a format of the data source to at least one alternative format. Original metadata is extracted from each data surrogate. New metadata is generated by combining portions of the original metadata and components of each data surrogate. The multi-dimensional surrogation generates an extended data surrogate comprising the data surrogate and the new metadata.

Claims

1. A computer-implemented method comprising:

generating at least one data surrogate using information of received data and a plurality of data changes received from at least one data source;

identifying relationships among portions of original metadata and components of each data surrogate and generating new metadata using information of the relationships;

generating an extended data surrogate comprising the data surrogate and one of the original metadata and new metadata; and

automatically controlling moving of at least one of the data surrogate and the extended data surrogate across a plurality of storage devices using a plurality of policies, wherein the plurality of policies comprise a placement policy that controls a location among the plurality of storage devices for storing the at least one of the data surrogate and the extended data surrogate, wherein the moving comprises archiving at least one instance of the data surrogate and the extended data surrogate in a storage device.

2. The computer-implemented method of claim 1, wherein the plurality of policies comprise a retention policy that controls a time for retaining the at least one of the data surrogate and the extended data surrogate.

3. The computer-implemented method of claim 1, wherein the plurality of policies comprise a disposition policy that controls at least one of time, event and method for disposing of the at least one of the data surrogate and the extended data surrogate.

4. The computer-implemented method of claim 1, wherein the plurality of policies comprise a filtering policy that controls filtering of the at least one of the data surrogate and the extended data surrogate.

5. The computer-implemented method of claim 1, wherein the plurality of policies define at least one parameter that controls the moving, the at least one parameter comprising at least one of source, content, key word, age, size, user, policies, frequency of access, inclusions, exclusions, and capture rules.

6. The computer-implemented method of claim 1, wherein the archiving includes placing at least one of the data surrogate and the extended data surrogate in a storage device as appropriate to an application to which the at least one of the data surrogate and the extended data surrogate corresponds.

7. The computer-implemented method of claim 1, comprising automatically controlling access to at least one of the data surrogate and the extended data surrogate using the plurality of policies.

8. The computer-implemented method of claim 1, wherein the plurality of policies complies with at least one of legal requirements and compliance requirements of retention, disposition, monitoring and supervision when multiple copies of at least one of the data surrogate and the extended data surrogate result from the moving.

9. The computer-implemented method of claim 1, comprising automatically controlling at least one of the generating at least one data surrogate and the generating an extended data surrogate using the plurality of policies.

10. The computer-implemented method of claim 1, comprising extracting the original metadata of each data surrogate according to the plurality of policies.

11. The computer-implemented method of claim 1, comprising enforcing access to at least one of the data surrogates and extended data surrogates through use of the plurality of policies.

12. The computer-implemented method of claim 1, wherein the generating at least one data surrogate includes generating additional data surrogates corresponding in part to data changes received from additional data sources.

13. The computer-implemented method of claim 1, wherein the at least one data surrogate is application-aware relative to an application corresponding to the received data and the plurality of data changes.

14. The computer-implemented method of claim 1, wherein the generating of the new metadata comprises combining the portions of the original metadata and the components of each data surrogate.

15. A data surrogate system (DSS) including:

a computer-readable medium encoded with a program, the program running on a processor and comprising,

a DSS server that receives data and a plurality of data changes;

an engine coupled to the DSS server that generates at least one data surrogate using information of the data and the plurality of data changes received from at least one data source;

an extractor coupled to the engine that identifies relationships among portions of original metadata and components of each data surrogate and generates new metadata using information of the relationships, wherein the extractor generates an extended data surrogate comprising the data surrogate and one of the original metadata and new metadata; and

a policy database coupled to the DSS server and comprising a plurality of policies, wherein the DSS server automatically controls moving of at least one of the data surrogate and the extended data surrogate across a plurality of storage devices using the plurality of policies, wherein the plurality of policies comprise a placement policy that controls a location among the plurality of storage devices for storing the at least one of the data surrogate and the extended data surrogate, wherein the moving comprises archiving at least one instance of the data surrogate and the extended data surrogate in a storage device.

16. The DSS of claim 15, comprising a policy console coupled to the policy database, wherein the policy console includes an interface by which the plurality of policies is generated and revised.

17. The DSS of claim 15, wherein the plurality of policies comprise a retention policy that controls a time for retaining the at least one of the data surrogate and the extended data surrogate.

18. The DSS of claim 15, wherein the plurality of policies comprise a disposition policy that controls at least one of time, event and method for disposing of the at least one of the data surrogate and the extended data surrogate.

19. The DSS of claim 15, wherein the plurality of policies comprise a filtering policy that controls filtering of the at least one of the data surrogate and the extended data surrogate.

20. The DS S of claim 15, wherein the plurality of policies define at least one parameter that controls the moving, the at least one parameter comprising at least one of source, content, key word, age, size, user, policies, frequency of access, inclusions, exclusions, and capture rules.

21. The DSS of claim 15, wherein the archiving includes placing at least one of the data surrogate and the extended data surrogate in a storage device as appropriate to an application to which the at least one of the data surrogate and the extended data surrogate corresponds.

22. The DSS of claim 15, wherein the DSS server via the plurality of policies automatically controls access to at least one of the data surrogate and the extended data surrogate.

23. The DSS of claim 15, wherein the plurality of policies complies with at least one of legal requirements and compliance requirements of retention, disposition, monitoring and supervision when multiple copies of at least one of the data surrogate and the extended data surrogate result from the moving.

24. The DSS of claim 15, wherein the DSS server via the plurality of policies automatically controls at least one of the generating at least one data surrogate and the generating an extended data surrogate.
