What's an elegant way of automatically backing up the contents of a large drive to multiple smaller drives that add up to the capacity of the large drive? (on Linux)
So I have a nearly full 4 TB hard drive in my server that I want to make an offline backup of. However, the only spare hard drives I have are a few 500 GB and 1 TB ones, so the entire contents will not fit all at once, but I do have enough total space for it. I also only have one USB hard drive dock so I can only plug in one...
