NASB
Figure 23-5 Example Configuration with Media Server as Data Mover
When the NASB is the data mover, it moves the data between the disks and the tapes. The NASB device
is a SCSI target device capable of handling SCSI Extended Copy (XCOPY) commands as well as a SCSI
initiator device capable of issuing read/write commands to disks and other backup media, such as tapes.
See Figure 23-6.
Figure 23-6 Example Configuration with NASB Device as Data Mover
The task of managing and preparing the source and destination targets is performed by the media server.
For example, if the destination is a tape library, the media server issues commands to load and unload
the correct tape and position of the tape write head at the correct offset within the tape.
