Does each amanda profile require a different holding disk location?

[Mike Fedyk]

I think I just found out why most of my backups are going over the end 
of the tape.

Here's a description of my setup:
   *
     Mon-Thu - Daily incremental with full level 0 backup every 7 runs
     on a rotation of 10 tapes. Each incremental level is on a minimum
     of two tapes in case of tape failure.
   *
     Friday - Weekly incremental with full level 0 backup every 4 runs
     on a rotation of 6 tapes.
   *
     Mon-Fri Daily incremental backup to hard disk on a rotation of 5 runs.
And they were all using the same holding disk with autoflush turned on.
I checked the files in the holding disk and the headers don't identify 
which profile they're associated with (probably for good reason -- what 
if you changed a profile name?).

So I have set up different holding disk directories for each profile.
Is this documented anywhere?
Thanks,
Mike
