one script does not work at crontab


I made a rsync backup at crontab, but this rsync backup script does not work.

Quote:
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
0 2,6,14,18 * * * root /root/backup_script/rsync_backup.sh
10 0,2,4,6,8,10,12,14,16,18,20,22 * * * root /root/backup_script/3.mysqldb_backup.sh
However "/root/backup_script/3.mysqldb_backup.sh" works.

Please let me know how to make rsync backup script works on crontab.

Thanks in advance.

For a start we'll need to see the code and you'll have to tell us exactly what the symptoms of "does not work" are; we're not mind readers.

You should put your cronjobs in /var/spool/cron/root not /etc/crontab or edit with

Code:
crontab -e
Well thats how I was taught

Can you run the scripts from the commandline

Code:
/root/backup_script/rsync_backup.sh
It could be your permissions on that script are not correct, look in /var/log/cron for any errors. Like chrism01 said, you should post the code.

jrosco/ Yes, I can run "rsync_backup.sh".

And "rsync_backup.sh" is this.

Quote:
#! /bin/bash
rsync -avr --delete --exclude lampp/tmp/* /opt/* /backup/opt/
rsync -avr --delete --exclude data/session/* /var/www/html/centos-vb/* /backup/centos-vb/
And the log part of cron is here.

The default env in cron is minimal to say the last. Best practice is to always specify complete paths to all cmds & files used unless you KNOW that the cron env will handle them correctly.... or specify a new env at the top of the script...

chrism01/ I changed and added env in cron as follows, but still not worked.

Quote:
#! /bin/bash

export PATH=/usr/local/bin:/usr/bin:/bin

rsync -avr --delete --exclude lampp/tmp/* /opt/* /backup/opt/
rsync -avr --delete --exclude data/session/* /var/www/html/centos-vb/* /backup/centos-vb/
