Abstract: A system and method for performing replication using mediums. A snapshot 'S' is selected for replication, and the anchor medium 'M' of S is identified. The replica storage array 'R' to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array 'O' and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.
