Check to see if the script is in fact making the tars.
If it is call it from you crontab using a line like this:
40 3 * * * /etc/back-res 1>/dev/null 2>/dev/null
This part of the line sends any output (such as error messages) to the 'bit bin'. That way you won't see them. As long as it does it's job then all is good.
I'm no expert on this, I can only quote from what works for me from advice from others so feel free to step in and comment anyone who knows better.
