Abstract

A method and system for archiving data based on a defined relevance attribute is discussed. This attribute may be based on the data's importance to a business or user. In an embodiment, more important data may be placed in high-end storage and less critical data may be placed in low-end storage.

First claim

What is claimed is:

1. A method for archiving a plurality of data objects, the method comprising:
associating a relevance attribute with at least one data object of the plurality of data objects, wherein the association of the relevance attribute is from an analytics engine;
associating a first relevance value to the relevance attribute of the plurality of data objects, wherein at least one data object of the data objects with an unassigned relevance value is assigned a default relevance value;
archiving the data objects to a first storage or a second storage based on the relevance attribute wherein the data objects having the first relevance value above a threshold value are stored in the first storage;
associating a second relevance value to the relevance attribute of the plurality of data objects, wherein the second relevance value is below the threshold value; and
migrating the data objects previously archived to the first storage having the second relevance value below the threshold value from the first storage to the second storage, wherein the first storage and the second storage are separate storage devices.

2. The method of claim 1 , further comprising selecting a high-end computer readable medium as the first storage when the first relevance value exceeds the threshold.

3. The method of claim 1 , further comprising selecting a low-end computer readable medium as the second storage when the first relevance value fails to exceed the threshold.

4. The method of claim 1 , wherein the first relevance value is received from a user.

5. The method of claim 1 , wherein the first relevance value is calculated based on a set of defined parameters.

6. The method of claim 1 , further comprising archiving the data object only when the data object has an associated relevance value.

7. The method of claim 1 , wherein the first relevance value is based on the data object's content.

8. The method of claim 7 , further comprising assigning the second relevance value based on changes to the data object's content.

9. The method of claim 1 , further comprising assigning the second relevance value based on changes to a second data object's content.

10. The method of claim 1 , wherein archiving the data object further comprises archiving a version of the data object for a plurality of relevance values.

11. The method of claim 1 , further comprising:
archiving a first version to a high-end computer readable medium when the first relevance value at least meets a threshold; and
archiving a second version to a low-end computer readable medium when the second relevance value at most meets the threshold.

12. The method of claim 1 , further comprising:
archiving a first version to a high-end computer readable medium when the first relevance value at most meets a threshold; and
archiving a second version to a low-end computer readable medium when the second relevance value at least meets the threshold.

13. The method of claim 1 , further comprising applying a retention policy based on the relevance attribute associated with the data object.

14. The method of claim 13 , wherein the retention policy comprises retaining a data object with a greater relevance value for a longer period than a data object with a lesser relevance value.

15. The method of claim 1 , further comprising notifying a user of the second relevance value before deleting the data object.

16. A computer program product for archiving a plurality of data objects, comprising a non-transitory computer readable medium having program instructions embodied therein for:
associating a relevance attribute with at least one data object of each of the plurality of data objects, wherein the association of the relevance attribute is from an analytics engine;
associating a first relevance value to the relevance attribute of each of the plurality of data objects, wherein at least one data object of the data objects with an unassigned relevance value is assigned a default relevance value;
archiving the data objects to a first storage or a second storage based on the relevance attribute wherein the data objects having the first relevance value above a threshold value are stored in the first storage and the data objects having the first relevance value below the threshold value are stored in the second storage, wherein the first storage and the second storage are separate storage devices;
associating a second relevance value to the relevance attribute of the plurality of data objects, wherein the second relevance value is below the threshold value; and
migrating the data objects previously archived to the first storage having the second relevance value below the threshold value from the first storage to the second storage.

17. A system for archiving a plurality of data objects comprising a non-transitory computer readable medium and a processor configured to:
associate a relevance attribute with at least one data object of each of the plurality of data objects, wherein the association of the relevance attribute is from an analytics engine;
associate a first relevance value to the relevance attribute of each of the plurality of data objects, wherein at least one data object of the data objects with an unassigned relevance value is assigned a default relevance value;
archiving the data objects to a first storage or a second storage based on the relevance attribute wherein the data objects having the first relevance value above a threshold value are stored in the first storage and the data objects having the first relevance value below the threshold value are stored in the second storage, wherein the first storage and the second storage are separate storage devices;
associating a second relevance value to the relevance attribute of the plurality of data objects, wherein the second relevance value is below the threshold value; and
migrating the data objects previously archived to the first storage having the second relevance value below the threshold value from the first storage to the second storage.
