It doesn't create anything under /home/apache/tactic_backup/postgresDb/
But when i run the script or command as root, it works and does the required. But via crontab it doesn't The crontab above is for root. Even in logs it shows that it ran(or so)

Any idea what i am missing?
Solution
My documentation states that the mentioning of the user (root in this case) after the time restrictions is only valid in the system crontab which is stored at /etc/crontab.
You are showing us users' crontabs (shown with crontab -l) which differ in that aspect; the user must not be given there, even if the user is root.
