I have a Pi3 at my parents home and I rsync over ssh to a 5 TB 2.5" spinning disc attached via USB, I added the disc to fstab. The first sync took over 24 hrs for ~550 GB [0]. We both have 100/100 fiber, but USB is limiting in this case, which is nice because it kept both our connections usable during transfer. Anyway, I had 0 issues. Well, apart from the fact that I initially used vfat as the FS of the target disc so my partner or parents could just pull out the disc and use it (on Windows/Mac) when something would happen to me. But this leads to rsync issues and needs workarounds so I switched it to ext4 and told my loved ones to find a Linux nerd in the event of my demise.
