It's a home server which is mainly being used for pictures and music. I 
thought 126k was abundantly enough for a server with this function. At 
normal usage lsof shows about 2100 entries.

# ulimit -n
1024

I guess this is probably the "fault", if you could call it that. The big 
question is, shouldn't 1024 file descriptors be enough to run a 
successfull backup?

My next question is more a matter of how I can set the ulimit so that it 
influences cron. As I mentioned earlier, I'm running Ubuntu 8.10.

I'm going to assume that this means that you consider it a bug. I'll 
wait for the response once you've had time to look into it more thoroughly.
