Dear Sirs:

I am an ISP in Honduras and I use TRAVAN tr-4 tapes for backup.
However I am having a large problem when issuing the unix dump backup
command.
Please send instructions for Free BSD Unix backup.... I am using 

/sbin/rdump 0dsfu 67733 740 /dev/nrst0 /

This starts fine but needs 3 cartridges to complete a backup of
a 4gb hard disk and this disk is only 7% full. One tape should be plenty
but somehow I am giving incorrect command from unix.

Please let me know the best dump command in unix to backup my unix
FREEBSD system.
