I see. If that's the order of your jobs, then it DOES look like small files
are going direct to tape.

Maybe your diskpool filled up during the night, and some clients had to go
direct to tape for that reason.  (Not too likely since your disk pool is
only halffull this morning...)

Maybe compression is fooling you, and the "small" files really were 5GB
before they got compressed.  I forget how TSM reports that...

Interesting question.
