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. Drivers that are associated with the instantaneous restore and utilize data-less writes are identified. A granularity value representative of a size at which the identified driver tracks changes is determined. Changed data extents in the first logical object are identified. Data-less writes are sent at the lowest determined granularity to any identified extents in the first logical object.
