Abstract
A storage system, including: (a) a primary storage entity utilized for storing a data-set of the storage system; (b) a secondary storage entity utilized for backing-up the data within the primary storage entity; (c) a flushing management module adapted to identify within the primary storage entity two groups of dirty data blocks, each group is comprised of dirty data blocks which are arranged within the secondary storage entity in a successive sequence, and to further identify within the primary storage entity a further group of backed-up data blocks which are arranged within the secondary storage entity in a successive sequence intermediately in-between the two identified groups of dirty data blocks; and (d) said flushing management module is adapted to combine the group of backed-up data blocks together with the two identified groups of dirty data blocks to form a successive extended flush sequence and to destage it to the secondary storage entity.
