AIX backup command not overwriting tapes

[ariochian]

Hi all,

I have a control workstation hanging off of 2 SP model frames, MCA and PCI types.

each node remote copies a mksysb file over a filesystem on the CWS and then on a Sat. morning, the cws is suppose to back up the files onto tape, however I have been noticing the date currently this tape shows Apr. 21 was the latest backup and each file on that tape is Apr 21. why isnt the backup command overwritting those file with new ones?


here is the back up commanding script (cut from smitty used in a corn shell script)

please help if you can. the only thing I can think of doing is a tctl -f /dev/rmt0 erase on the friday night before the backup on Sat.

#MKSYSB
#SAVES FILES LOCATED IN "nodebkups"
#TO 8mm TAPE
x() {
ARGS=''
LOCAL=''
while getopts 'b:f:lps:v' OPTION; do
case $OPTION in
b) cd $OPTARG || exit $? ;;
f) DEVICE=$OPTARG ;;
l) LOCAL='-fstype jfs' ;;
p) ARGS=$ARGS' -p' ;;
s) SOURCE=$OPTARG ;;
v) ARGS=$ARGS' -v' ;;
esac
done
/usr/bin/find $SOURCE $LOCAL -print |
/usr/sbin/backup -iq -f $DEVICE $ARGS
}
x -f'/dev/rmt0' -s'/nodebkups/f1n1files/bos.obj.f1n1 /nodebkups/f1n5files/bos.obj.f1n5 /nodebkups/f1n9files
