Abstract
A technique of managing storage includes receiving a request to change an initial portion of data, the initial portion of data (i) associated with an initial redundant region and (ii) including a first segment to be changed and a set of other segments not to be changed; updating the first segment in response to the request; and generating an updated redundant region based on a computation involving the initial redundant region and the first segment but not involving the set of other segments.
