Ecasound is the perfect tool for this. We have used it for several
years (six or so) to do several unattended recordings *a day* with
only a handful of broken recordings through all these years (which
weren't ecasound's fault generally, but more like: Someone stepped on
an important cable etc.)

Besides -t also the -z option is useful to switch on double buffering
and of course "-rt" should be used to have ecasound run at realtime
priority to further reduce the risk of dropouts. 

You start ecasound through crond then. It's also a good idea to
somehow set the clock in advance. We just used netdate some minutes
before starting to record to synchronize the clock.

Ciao
