You want to do a backup at 1am every day?
Check how you have set up your cron environment
http://www.adminschoice.com/docs/crontab.htm

*.sh files are not normally binary. By convention, binaries do not have an extension.

Well you can try - it should not make any difference.
Who is supposed to own the cron session for that program? Root? You? Who?

root is the owner of that session

Then log would normally be

SESSION OPENED FOR ROOT

see?

Have you checked your cron environment yet?
