Direct Tape Connection
The simplest site model is the one where we connect our
tape device directly to the machine we are going to back up (see Figure 4).
One advantage this setup
is the speed of the link between data and backup device (typically SCSI)
versus the network connection used in other models.
The disadvantages of
this model are limited scalability, manageability and hardware cost (one
tape device needed for every server). This setup can be suited for sites
with a limited number of machines that need to be backed up.
