Interesting. That strategy has the possibility to trigger both bans - both the “maximum one >100GB blob/day” ban and the “maximum 750GB/day” ban.
Please let us know how long it took you to finish the transfers, once they are done. The experience so far is that the transfer rate is severily throttled, once the 750GB/day ban kicks in.
In your case, I presume the bans will kick in once the first 1TB file transfer is done.
