I use this configuration.
You use this configuration specially if you have a small backup window and
an a service agreement with your clients.

We have a service agreement that users can recover their data without our
intervention. And that It has to be fast.
Naturally you cannot keep it forever on disk. So it is agreed witihin my
organisation that recovery will be "fast" for a month.

So I backup it to disks and run a script to stage all saveset beyond that
time to free up space.

You can do that if you want fast recovery. People will say that tape
technology pretty fast now. But I find out that it is not as fast as tape.
