Given your description here, I'm not really sure if you really even
care about every single line of output from this background process.
I just get the idea you want to check up on it every once in a while.

So....given this....you could just run your program under "screen".
After you've started running the program, detach from the "screen".
It will continue to run.  Later on you can reattach with "screen -r".
Etc.

...

Sometimes I leave long-running compute jobs running under screen.
Start them in one physical location.  Later, in some other location, I
re-attach and look at my output.

Hope this helps,
