MTree replication is also generally faster than directory replication and is recommended by Dell EMC in order for customers to take advantage of increased replication .2 or later source is configured to replicate to a target running DDOS 6.The likely reason for this is that the snapshots are still required to be kept on the system by something like mtree replication - in this case DDFS 'softlocks' the snapshot so even if its expired its not removed during clean (as if it were removed it would break the functionality of which ever feature was using it). The mtree replication will only copy blocks from the source to the target which do not exist on the target. The mtree should be replicated to the DR . A large replication lag is causing the data to not be removed during the cleaning.
