Multi-tier file storage management using file access and cache profile information

In one embodiment, a method includes receiving a list of applications that are anticipated to access a given data block within a time window with an anticipated future access count for each anticipated application. The method also includes determining that a block application access weight is greater than a block application access threshold, the block application access weight being based at least in part on the anticipated future access count for each anticipated application. The method further includes determining that a cache profile weight for the given data block is greater than zero contingent upon the block application access weight being greater than the block application access threshold. Moreover, the method includes sending the cache profile weight to a file system contingent upon the cache profile weight being greater than zero. Other methods, systems, and computer program products are described in accordance with more embodiments.
