Is there any message in your mail?
Is there enough space in /tmp to create temp-files en log 4 the backup?
Try running the backup script on the command line with the log redirected as
you do
and see if it runs fine then you know if the problem is the cron or the
script!
Are you sure the script is executable? (i.e. # chmod 700 /tmp/bkup/bkup_
skripta)
You can start mksysb with -X to auto-expand /tmp.
This is my cron entry:
0 19 * * 1-5 /usr/local/backup/backup.sh
This is my backup script in short:
LOG="/usr/local/log/backup_RS-EV1.log"
DEV="/dev/rmt1"
# Rotate logfiles:
mv $LOG.13 $LOG.14 >/dev/null 2>&1
mv $LOG.12 $LOG.13 >/dev/null 2>&1
mv $LOG.11 $LOG.12 >/dev/null 2>&1
mv $LOG.10 $LOG.11 >/dev/null 2>&1
mv $LOG.9 $LOG.10 >/dev/null 2>&1
mv $LOG.8 $LOG.9 >/dev/null 2>&1
mv $LOG.7 $LOG.8 >/dev/null 2>&1
mv $LOG.6 $LOG.7 >/dev/null 2>&1
mv $LOG.5 $LOG.6 >/dev/null 2>&1
mv $LOG.4 $LOG.5 >/dev/null 2>&1
mv $LOG.3 $LOG.4 >/dev/null 2>&1
mv $LOG.2 $LOG.3 >/dev/null 2>&1
mv $LOG.1 $LOG.2 >/dev/null 2>&1
mv $LOG $LOG.1 >/dev/null 2>&1
/usr/bin/mksysb -X -m -p $DEV >>$LOG 2>&1
Good luck
Marc
