i am very sorry if this has been asked before... i'm sure it has.. but i have searched all over the net looking for an answer and i still cant find it... so somebody pleeeeease help me! I have a really simple cron job script like this: cd /var/www/vhosts/ tar -cvzf /backup/myhttpdocs-backup-`/bin/date +\%Y\%m\%d`.tar mywebsite.com.au/httpdocs/ when i run this manually it works fine but when i run it from my ROOT user in Plesk as a cron task is always creates a file that is just 45 bytes. Why doesn't it work... I am running it as a root user.. so surely i must have permission to access the files?!!! Its driving me nuts. oh yeah and PS... my /backup folder is chmod 777 the full path to the directory i want to backup is: /var/www/vhosts/mywebsite.com.au/httpdocs/ and again... IT WORKS when i log in as root user using ssh. So why wouldn't it qork when i run it as a cron task?
