You can use volume SnapMirror to replicate a deduplicated volume regardless of size of the volume and logical data in the volume.
When using volume SnapMirror with deduplication, you must consider the following information:
When configuring volume SnapMirror and deduplication, you should coordinate the deduplication schedule and the volume SnapMirror schedule. You should start volume SnapMirror transfers of a deduplicated volume after the deduplication operation is complete. This schedule prevents the sending of undeduplicated data and additional temporary metadata files over the network. If the temporary metadata files in the source volume are locked in Snapshot copies, these files consume extra space in the source and destination volumes.
