[SOLVED] System Backups

[mcrognale]

I'm having a bit of trouble backing up the OTRS appliance. I can run /sbin/backup.pl from the command line and it dumps the ISO into /BACKUP as expected. The problem occurs when I attempt to run the backup through cron:

0 4 * * * /usr/bin/perl /sbin/backup.pl

I get this error in syslog:

(CRON) error (grandchild #23797 failed with exit status 255)

And this is what shows up in /var/log/backup.log

what user is running cron? Make sure it's the otrs user.

[mcrognale]

It's running as the root user. I get all kind of permission denied errors when I attempt to run the script as the otrs user. It will only successfully backup running as root from the command line.

I'm not sure how the appliance works. I thought the otrs backup utility was within /opt/otrs. Please excuse the interruption. Perhaps someone else might be of assistance.

[mcrognale]

I gave up on getting the /sbin/backup.pl script that's included with the appliance to work. I switched over to /opt/otrs/scripts/backup.pl and things are working as expected.
