It denpends on the data but gzip is okay, bzip2 is usually better
and lzma (of 7zip fame) tends to be best. lzma does have a heavy
CPU penalty but as you don't care then you are okay.

Sometime a specialised compression engine will work better as it
has a better "dictionary".

Given cheap high capacity hard disks why do you need to squeeze
the last few bytes out of your files? If you don't mind me asking?
