set uid question w/ backup script

this is the backup script. When i run it as a non root or authority user i get the following errors for each filesystem being backedup. It then continues to the next fs. Do i have this set up correctly? am i missing something?

backup: The backup command has ended abnormally.
backup: 0511-225 Cannot open /dev/rmt0.1.
Operation not permitted.

Code:

#! /bin/ksh
#
#       This script is intended to be used on AIX 4.3.3 and 4.3.2 ONLY.
#       This will use the backup utility doing a level 0 dump on any filesystem defined for $filesys and update /etc/dumpdates.
#       Arguments:
#               DEVICE = backup device rmt0 = rewinding rmt0.1 = non-rewinding
#               DUMPINFO = file that will collect info to be emailed out
#               MARK = possition on the tape
#

DEVICE="/dev/rmt0.1"
DUMPINFO=/tmp/dumpinfo
FILESYSTEMS="/ /usr /var /home"
MARK=1

echo > $DUMPINFO

for filesys in $FILESYSTEMS; do
        echo "Date: `date`
Filesystem: $filesys
Position: $MARK
Device: $DEVICE
        " >> $DUMPINFO
        /usr/sbin/backup -f $DEVICE -0 -u $filesys >/dev/null 2>&1
        MARK=`expr ${MARK} + 1`
done
cat $DUMPINFO|mailx -s "Dumpinfo `hostname`" root
sleep 20
mt -f $DEVICE rewoffl

Script Perms:
-r-sr-sr-x 1 root system 850 Aug 09 17:11 /var/adm/scripts/backup.ksh

Backup command perms (just incase needed):
-r-xr-xr-x 1 root system 4320 Dec 24 1998 /usr/sbin/backup
