Abstract: Apparatus and method for scheduling the storage backup of data sets in either an application or system-managed storage context using an algorithm in which less data and a smaller backup interval (window) are involved other than that used with prior art FULL, INCREMENTAL, or COMBINATION backup policies. The invention is premised on an INCREMENTAL backup policy sensitive to a pair of adjustable parameters relating to the last backup, last update, and current date affecting each data set and its storage group.
