I am trying to create hourly backups using a makefile, which uses rsync internally. (* */1 * * * backup.sh). Backup.sh is in my home folder. The reason I'm using a makefile is because I also do a backup on my portable disk apart from my remote server, and using a makefile enables me not to rewrite the same script again.

The problem is: The makefile is unable to run when called from cron. Cron and makefile, when called individually, works like a charm. But the whole thing doesn't work as a unit. Since the cron would run at the backend, I have put silent/quiet modes for make/rsync. But even that doesn't solve the problem.

Any help would be appreciated.

Thanks in advance, Royzz

Your description is too vague. Please provide error messages or the email cron sends you when the job produces output. Wild guess: some environment variables are missing. A cron job has almost an empty environment. If you can run your cronjob with env -i ./script.sh then you're ready for cron. – Jens Aug 29 '11 at 12:14
