Techopedia Explains Target Deduplication

Target deduplication is primarily a data deduplication technique for backup data or secondary data. Typically, target deduplication works when the data reaches the target storage device. The actual deduplication, after reaching its target, can be done either before or after the data is backed up on the device. Target deduplication eliminates data deduplication from the client device, but it requires higher bandwidth to receive the redundant data. It is used by virtual table libraries (VTL), intelligent disk transfer (IDT) and LAN B2D appliances and devices.
