dump needes 35 DAT-tapes?

[Lukwata Dominic <lukwata roxi rz fh-mannheim de>]

Hi,

I have been making backups of my RH 6.1 with dump. 
But the dump progam has been estamting too many 
DAT-Tapes as needed!

e.g. for /usr (around 2GB) dump estimated around
35 DDS-2 tapes (120m: 2GB uncpressed). Now I knew that 
the total needed tape capacity does not exeeed 2 GB.
Therefore I just stopped the program as it asked for a
next tape. 

Sometimes the "dump" estimates a negative number of needed
DAT tapes.

Does any one knows how to put this right. 

Thanks

Dominic
