It’s good practice to have redundant backups. Aside from +Drive, my C6 sysex dumps are saved in a Dropbox folder. I can access it anywhere, and the files are saved locally on my computer.
Juuuuust in case.

I often imagine a scenario where I get to a city for a gig and there is an issue with my equipment, and am able to find a Rytm and A4 locally for the gig, I just dump my sysex from the cloud and I am still able to perform. Mind you, I’ve done everything in my power to prevent issues with equipment when traveling (always have gear in carry-on luggage, etc), I still need a backup plan. sysex dumps to a cloud is my backup.

I also keep write protected copies of my live projects on the +Drive. And perform from those, so that I don’t mistakenly edit them.
