afio does notice that certain file types are already compressed and
doesn't bother trying to compress them again. You can also choose a
minimum file size to compress (if little will be gained from
compressing it). And, -P lets you choose the compression program. I
use bzip2. I've seen others pipe it through gpg for encryption.
I've been using afio for close to a decade and never lost anything,
but I'm sure others can say the same for tar.
