Patent abstract

A method is used in managing restore operations in storage systems. A state of a logical object is retrieved and a second logical object is placed in a pre-step mode. An instantaneous restore operation between the first logical object and the second logical object is performed. Changed data extents in the first logical object are identified. Data-less writes are sent to any identified extents in the first logical object.
