I don't use disk-based backups, but I have read a couple of times how 
file-based volumes aren't truncated or over-written when new data is written 
to them.

As I don't use disk-based backups, I can't get into specifics, but I believe 
that if you:

2.  Create a labeling schema that will create a NEW volume for each job 
(perhaps something that will include a date, like "Wednesday5_30Nov07" you'd 
get volumes more in line with the sizes you're expecting.

3. Write a RunBefore script for each day's job that will delete any old 
volumes, free-ing up space on your disk(s) for the new backup you're running.

I think File-based volumes require that kind of file-management interaction.  
I'm sure folks who work with them more will chime in with 
details/corrections.
