Have you looked at campware? It provides open source software solutions to
run radio stations:


Not sure if it supports the sound backup you are wanting.

A simple bash script calling arecord to save date and timestamped files for
a fixed duration should be able to do the job though (as long as you are
using alsa!).

something like:

while [ 1 ]
   arecord -d 86400 -r 44100 -t wav soundbackup`date "+%H%m%d%y"`.wav

(haven't tested this so it may not work, but you get the idea!)
