Maybe you are missing the #!/bin/sh line at the beginning? I am not sure
whether it is needed in that situation. It certainly wouldn't hurt.
However, if you only backup world-readable files I suggest you to run
'crontab -e' as normal user and add
@daily ~/bin/myscript.sh
# EOF
to the file (whether it's empty or not). Make sure you have an empty or
commented line at the end of the file.
That way you make sure you don't have root-owned files on your home
directory and you don't use root privileges without a reason.

Well, because it's in the cron.daily folder, the script should run
daily. That's generally fine.
