I am not sure how hard it would be to add this to bacula. Although I believe one feature request may lessen the need for this if it gets implemented. I mean multithreaded client where each thread operates on a single file. This way you can have 4 to 6 threads on a 4 core system and not need to do parallel compression.
I am still waiting for a completely different operating system feature that would solve the same problem for me. This is something that I did on windows 10 years ago. I mean have the filesystem compress the files on the storage. Not automatic compression on every write, but I mean a cron job that can tell the os that a file should be compressed now. Run this compression on the storage when the server is not doing backups. This would be totally transparent to bacula but it would require a much beefier server.
