dump config for 4mm DAT SCSI

[Alex Vorobiev <sasha forum swarthmore edu>]

RH 5.1 
NetServer LH Pro w/SureStore DAT24

My approximate configuration based on the tape capacity 
(in this case, using a DD2 120m tape):

/sbin/dump 0nuBf 4000000 /dev/nst0 FILESYSTEM

works well.  I was wondering, however, if anybody had more 
precise tips/best practices.  Also, how does one control 
compression?  mt -f /dev/nst0 returns nothing (is it supposed to,
or does this set compression to ON?).

Thanks!
