Have you looked at campware? It provides open source software solutions to run radio stations: http://www.campware.org/ 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!)
