Compare backup image metadata on the Source DD and the Target DD.
Copy/make note of the backup_image name.
On source DD enter the following command:
mtree list
domain@dd1# mtree lis
Name Pre-Comp (GiB) Status
----------------------------- -------------- ------
/data/col1/storage_unit 4678.6 RW
/data/col1/storage_unit_2 79.5 RW
/data/col1/storage_unit_3 0.0 RW
/data/col1/storage_unit_4 19868.9 RW
----------------------------- -------------- ------
copy the mtree file path of the mtree that is in use.
use the following command:
filesys show compression /data/col1/storage_unit/*backupimage_1478584827*
domain@dd1# filesys show compression /data/col1/storage_unit/*backupimage_1478584827*

This command will give you a break down of the meta data for the specific image you have searched. Run the same commands on the Target DataDomain and see if there are any differences.
I've had it where only partials of the meta data is replicated and the source doesn't know what to do and then the replication fails.
