If you manage 5 or 10 machines and have a nice tape backup, you don't need
Pools, and you may wonder what they are good for. In this chapter, you will
various different Volumes to meet their needs.
The rest of this chapter will give an example involving backup to disk

the expense here is a few GB which is not too serious.
