Managing data across a plurality of data storage devices based upon collaboration relevance

A system for managing data, the system comprising:

• a memory storing computer-usable program code that, when executed, selectively manages data storage among a plurality of data storage devices;
• and
• a processor executing the computer-usable program code, wherein the processor:
• determines collaborative activity for each of a plurality of data items associated with a first user and stored within a first data storage device;
• calculates a measure of relevancy for each of the plurality of data items according to the collaborative activity;
• compares the measure of relevancy of each of the plurality of data items to at least one relevancy threshold;
• and
• selectively migrates different ones of the plurality of data items from the first data storage device to a second data storage device according to the comparison of the measure of relevancy of each of the plurality of data items.

A computer program product comprising:

• a computer-usable medium comprising computer-usable program code that, when executed by a computer, manages data storage among a plurality of data storage devices according to collaborative activity, the computer-usable medium comprising:
• computer-usable program code that determines collaborative activity for each of a plurality of data items associated with a first user and stored within a first data storage device;
• computer-usable program code that calculates a measure of relevancy for each of the plurality of data items according to the collaborative activity;
• computer-usable program code that compares the measure of relevancy of each of the plurality of data items to at least one relevancy threshold;
• and
• computer-usable program code that selectively migrates different ones of the plurality of data items from the first data storage device to a second data storage device according to the comparing the measure of relevancy of each of the plurality of data items.
