rsnapshot in script

[Roger Beever <roger2 rogernet net>]

Hi
I have been using rsnapshot for a while and would like to put it in a
script to help automate things a bit more but I'm not up in scripting at
all.
The script would call rsnapshot hourly (name of the routine not
literally every hour).
But the real stopper is the how to respond in the script to the password
request.
Any pointers or a illustration would be greatly appreciated.
Regards Roger
