If you are running bacula 15.x, they added zstd compression. In my tests zstd compression was as fast as lzo and as good as gzip. So if you can try zstd in bacula 15.x, I definitely recommend it.
Otherwise, your choices for software compression are: gzip: good for space saving, but slower. lzo: less space saved, but faster than gzip. Definitely better than nothing.
