Abstract
A mechanism for efficient delayed replication is described. A method of embodiments of the invention includes detecting input/output (I/O) requests issued by a software program running on a computer system, and sorting the I/O requests into I/O batches according to flight overlapping of the I/O requests. An I/O batch includes a set of flight-overlapped I/O requests of the I/O requests. The set of flight overlapped I/O requests includes two or more I/O requests that are issued, at least partially, in parallel. The method further includes replicating the I/O requests to a storage medium coupled to the computer system.
