Abstract
A method involves generating a block-level write operation, which causes a value to be written to a primary volume, and generating information indicative of whether any of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume. The information can indicate that all, part, or none of the block-level write operation should be transferred to the secondary site. If the information indicates that less than all of the block-level write operation should be transferred to a secondary site, the information can also indicate that logical information associated with the block-level write operation should be transferred to the secondary site instead of transferring the value being written by the block-level write operation.
