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:
#!/bin/bash
while [ 1 ]
do
arecord -d 86400 -r 44100 -t wav soundbackup`date "+%H%m%d%y"`.wav
done
(haven't tested this so it may not work, but you get the idea!)

please excuse the random spewing of ideas:
i work at a radio station, and it would be awesome if i could record
insanely long periods of time (for quality control).
i'd love to be able to record 24/7, with new audio replacing old. a
400gig drive could hold two weeks of 16-bit 44.kHz stereo audio. how
long could it survive constant writing?
alternatively, are there any one-line commands that will simply record
continuously to a series of files until a partition runs out of space?
