Abstract

Embodiments of this disclosure managing storage of files, stored in a computer storage system having policy-based file storage management, using information derived from content of the files. Embodiments execute content analytics logic module(s) on a primary file stored in a base storage system, creating one or more Features derived from the primary file content. Based on the Feature(s), embodiments automatically determine an electronic storage policy for the primary file and, in certain embodiments, also for the Feature(s). The Features, and accordingly the storage policy, can be updated particularly readily in exemplary embodiments having pluggable content analytics logic modules. This may be occur in light of, for example, new content analytics algorithms (e.g., new image analysis algorithms), new external factors (e.g., new rules governing certain content), and/or new storage equipment (e.g., new storage farms for which it may be more useful or cost effective to store certain types of data).

Claims

1. A method of managing storage of electronic files using information derived from content of the electronic files, wherein the electronic files are stored in a computer storage system having policy-based electronic file storage management, the method comprising:

executing at least one content analytics logic module on a primary file stored in a base storage system to create one or more Features derived from content of the primary file, wherein the primary file is stored in the base storage system by an external system coupled to the base storage system; and

automatically determining an electronic storage policy for the primary file based on the one or more Features.

2. The method of claim 1, further comprising:

linking the primary file to the one or more Features such that an identical storage retention policy applies to both the primary file and at least one of the one or more Features.

3. The method of claim 2, wherein the identical storage retention policy triggers automatic deletion of the primary file and at least one of the one or more Features after expiration of an audit-based retention period.

4. The method of claim 1, further comprising:

linking the primary file to at least one of the one or more Feature such that a storage retention policy for the primary file applies to the at least one of the one or more Features while a storage retention policy for the at least one of the one or more Features does not apply to the primary file.

5. The method of claim 4, wherein the storage retention policy for the primary file triggers automatic deletion of the primary file and at least one of the one or more Features after expiration of an audit-based retention period.

6. The method of claim 1, wherein creating one or more Features derived from content of the primary file comprises:

creating a first Feature, wherein the first Feature is metadata derived from the content of the primary file; and

creating a second Feature, wherein the second Feature is a derived file, and content of the derived file is based on the content of the primary file, and wherein the method further comprises;

determining a storage policy for the primary file and the derived file based on the derived metadata.

7. The method of claim 1, further comprising:

storing the derived metadata in an index in the base storage system; and

storing the derived file in the base storage system.

8. The method of claim 1, wherein creating one or more Features derived from content of the primary file comprises:

creating metadata derived from the content of the primary file.

9. The method of claim 8, wherein the primary file is an image produced by a machine that generates multi-modal data and the derived metadata represents a categorization of content in the image.

10. The method of claim 1, wherein the primary file is one of a plurality of primary files of differing modalities stored in the base computer storage system.

11. The method of claim 1, further comprising:

automatically determining an electronic storage policy for at least one of the one or more Features based on the electronic storage policy automatically determined for the primary file.

12. A system comprising:

a base storage system coupled to an external system, the base storage system to store a plurality of primary files of differing modalities, wherein one of the plurality of primary files is a primary file received from the external system, and wherein the base storage system is configured to provide policy-based file management; and

a content analytics platform coupled to the base storage system, the content analytics platform comprising;

a content analytics logic module plugged into the content analytics platform and configured to create one or more Features derived from content of the primary file received from the external system; and

an Feature manager logic module coupled to the plugged-in content analytics logic module and configured to select an electronic storage policy for the primary file based on the one or more Features and to link the one or more Features to the primary file such that a storage policy for the primary file applies to the one or more Features.

13. The system of claim 12, wherein the one or more Features includes a first Feature and a second Feature, wherein the first Feature is metadata derived from content of the primary file and the second Feature is a derived file, wherein the derived file is smaller in byte size than the primary file and content of the derived file is based on the content of the primary file.

14. The system of claim 12, wherein the one or more Features includes a first Feature, wherein the first Feature is metadata derived from content of the primary file, and the system further comprises:

a second content analytics logic module plugged into the content analytics platform and coupled to the Feature manager, the second content analytics logic module configured create a second Feature, wherein the second Feature is a derived file, and wherein the derived file is smaller in byte size than the primary file and content of the derived file is based on the content of the primary file.

15. The system of claim 12, wherein the content analytics platform further comprises:

a query interface configured to receive a query for Features and, in response, retrieve one or more Features and corresponding primary files based on the query.

16. The system of claim 12, wherein the base storage system comprises:

a first storage medium; and

a second storage medium,

wherein the first storage medium is more expensive than the second storage medium, and

wherein the Feature manager logic module is configured to select between a first electronic storage policy identifying the first storage medium as a storage location for the primary file and a second electronic storage policy identifying the second storage medium as the storage location for the primary file based on the one or more Features derived from the content of the primary file.

17. A computer program product for policy-based computer file life-cycle management based on content-based analytics, the computer program product comprising:

a computer usable storage medium having computer usable program code embodied therewith, the computer usable program code comprising;

computer usable program code configured to execute at least one content analytics logic module on a primary file stored in a base storage system creating one or more Features derived from content of the primary file, wherein the primary file is stored in the base storage system by an external system coupled to the base storage system; and

computer usable program code configured to automatically determine an electronic storage policy for the primary file based on the one or more Features.

18. The computer program product of claim 17, wherein the computer usable program code further comprises:

computer usable program code configured to link the primary file to at least one of the one or more Features such that a storage retention policy for the primary file that triggers automatic deletion of the primary file also triggers automatic deletion of the at least one of the one or more Features after expiration of an audit-based retention period.

19. The computer program product of claim 17, wherein the computer usable program code further comprises:

computer usable program code configured to automatically determine a first storage medium for the primary file when the one or more Features indicates a first categorization of the primary file content and a second storage medium for the primary file when the one or more Features indicates a second categorization of the primary file content.

20. The computer program product of claim 17, wherein the computer usable program code further comprises:

computer usable program code configured to determine a storage policy for one of the Features based on another one of the Features.
