I kinda figured out the source of slow speed: it's Wifi-network on 2.4GHz; they say it works well on 5GHz. There's no wish to upgrade to 5GHz; I guess it's gonna be less trouble to connect this computer to the external HDD using a USB-cable.* Yes, 1% in 21 hours IS slow. I guess your are copying a lot of small files to a NAS?
Why it wants to copy all over again (full) even with incremental checked on some other computer on cable network, might be because of checkbox "Create separated backup using timestamps". I unchecked that, and will test again on weekend.
