A computer program product, system, and method for generating coded fragments comprises intercepting I/O writes between a host and a logical unit (LU), sending the I/O writes from a first site to a second site, writing the I/O writes to one or more journal files within a deduplicated storage system at the second site, generating a snapshot of the LU within a deduplicated storage system at the first site, and replicating the snapshot from the deduplicated storage system at the first site to the deduplicated storage system at the second site.
