Hi,please check:
1. Whether the system date is today, you mean only Friday do the backup;
2. Manually run the "fbackup -f ...",what's the result?
3. Check /var/mail/root for errorlog!

good luck!

please check the /var/adm/cron/log, does it record your previous cronjob.

1. create script (backup_cmd.sh)like this:
fbackup -f /backup/app.`date '+%y%m%d'` -0i /tmp/demo -I
2. edit crontab as follows:
50 13 * * 5 backup_cmd.sh

Sorry for the connection problem above.

never run a script or program from cron that does contain the full path. i.e. /usr/sbin/fbackup

You may get an indication from root's mail. The other thing to be sure of is that the program or script has executable permissions. In the command your using, it will be a path problem.

It's ok now.

# more /backuporadata/backu01
fbackup -f /backuporadata/oracle.app.`date '+20%y%m%d'` -0i /u01
# crontab -l
59 23 * * 5 /backuporadata/backu01

Kevin,
you need to escape the % characters in your crontab command. See crontab(1) for details of why this is necessary.

The correct version of the command is:

50 13 * * 5 fbackup -f /backup/app.`date '+\%y\%m\%d'` -0i /tmp/demo -I index.tmp

HTH,
Michael.
