How to make a backup from my projects, patterns and sounds

Hi there. Last week I finally thought to have found how to manage and backup my projects including sound & patterns. Yes, I discovered the Elk-Herd application, which looked to good to be true. Normally a good application I guess. But the problem is that I upgraded both overbridge and digitakt, so fetching a project does not work. HELP! I also tried the sysex librarian, but also this way I cannot manage to send files from my digitakt to my computer.
C6 doesn’t run on my macbook anymore. And with the overbridge transfer, I suppose you cannot backup your projects inclusive the rigth sounds and rhythm?? It is not only backing up, but also managing my patterns & projects ( I would like to copy certain banks from 1 project to another for example ). Can anyone tell me what is the easiest / possible way to do this please?

Have you tried the Transfer app?
