Abstract
A replica site is restored to a selected point in time by determining data state at the selected point in time, writing data indicative of that data state to the replica site storage array, and moving extents of the data written to the replica site storage array to selected tiers in order to achieve a predetermined level of performance. A journal of statistical meta data indicative of IO activity may be used to select the tiers.
