Third-Party Copy Device
A backup agent on the SAN that operates on behalf of backup applications. The third-party copy device receives backup data from a disk attached to Fibre Channel and sends it to a storage device, by using the SCSI Extended Copy command. The third-party copy device is sometimes called a copy manager, third-party copy engine, or data mover. In SAN hardware configurations, a third-party copy device can be implemented as part of a bridge, router, or storage device. The third-party copy device may or may not be the device to which the storage units are connected.
