problem using 'dump' from cron

Hi Everybody,

I have a problem, my script works absolutely fine when run interactively, and
even in the background using nohup, but it fails when run by cron (as root).  

It tells me that 'dump' terminated with error code 1.

Also, I wanted to redirect the output from the dump command into a file, 
which I would have the script mail to me if anything went wrong, but it doesn't
like that either. If I redirect standard output, nothing appears there, if I 
redirect error output, it complains about ambiguos redirection.
I have tried in the crontab entry to redirect the output of the script to both a
file and null with to no avail. 

I am new to the NeXT's so I may overlook something obvious.
Any suggestions?

Thanks
