There's an application targeted at recording audio continuously in
chunks of 1 hour length called 'rotter':

http://www.aelius.com/njh/rotter/

I didn't use this application for quite some time, so I don't know
whether this program still does what you are looking for. But at the
time I used the program it just worked: lightweight and solid.

rotter requires that you run the jack audio server (you would let jack
run all the time).

For sure there are other (better?) options that I don't know of, but
your goal (continuously in 1 hour chunks) seems to be exactly what
rotter was built for...
