Yup. I used to work for a much smaller tech company, and we had a perfectly reasonable process for dealing with cour orders and search warrants that involved crazy things like “get it in hard copy”, and “verify the information contained in the order”.
For some things, we would even just ask the officer to physically come in and that was weirdly never a problem.

You might end up splitting files across drives, but I don’t think you’re likely to find a more “out of the box” solution. You might combine it with the compression flags to make sure things fit, and don’t forget to number your drives!
