That sounds very acceptable to get those files backed up.
It shouldn't stress things to spend a couple weeks relaying a terabyte in small chunks. The most likely strain is on my upload bandwidth and yeah that's the cost of cloud backup, more ISPs need to improve upload.
I mean, cycling a couple of terabytes of data over a 512GB drive is at least full 4 writes, which is too much for that kind of thing.

I was yelling the same things to the void for the longest time, then I had a brilliant idea of reading the technical specs of the technology coming to my home.
Lo and behold, the numbers I got were the technical limits of the technology that I had at home (PON for the time being), and going higher would need a very large and expensive rewiring with new hardware and technology.
