DataDomain boost is supported in NetWorker 7.6.1 or above. With clone from boost to boost devices, it is no longer a one to one ratio. You can have more than one read session from the same boost NetWorker readonly device. Also, multiple clone jobs can write to the same boost device at the same time. Of course, it is not recommended to allow more than 4 sessions at the same time per boost device.
At the same time, it only sends the delta to the clone destination (given the destination is boost device). This shorten the time for cloning after backup.
If the read or write media are not boost device, it should fall back to the one to one ratio (legacy way).
However, be very careful if your storage node is a very busy storage node, for example, SQL cluster. Because dedup happens on the storage node (storage side dedup), this can cause heavy CPU usage. So, best option is to config your SQL cluster as dedicated storage node with AFTD.
