[PLUG] Copying files to multiple volumes

[Walt Mankowski via plug <plug@lists.phillylinux.org>]

Hi,

At work I've got to copy 7.8 TB of files onto external hard drives so
they can be archived. Ideally I'd like these to fit onto two 4-TB
drives. Assuming they can fit [1] does anyone know of a way to do
copies that span volumes?

My fallback is to run `du -b --max-depth=1`, load the output into a
spreadsheet, and hope that I can find point in the middle that leaves
half on each side. But I'm hoping there might be something to automate
it.

1. Yes, I realize this is the bin-packing problem and it's
   NP-Hard. The subdirectories are all around the same size and I'm
   hoping I'll get lucky.
