Abstract
A data block storage management capability is presented. A file system includes a plurality of data blocks which are managed using a first storage service and a second storage service, where the first storage service has a lower storage cost and a higher input-output cost than the second storage service. The data blocks stored using the second storage service have associated therewith respective expected storage durations indicative of respective lengths of time for which the data blocks are to be stored using the second storage service (which may be the same or different across the ones of the data blocks stored using the second storage service). The expected storage durations of the data blocks are modified based on a comparison of an expected hit rate of the second storage service and a current hit rate of the second storage service or current hit rates of the data blocks.
