Outside my depth but I'll give it a stab. Identify what data is important, (is the full 42Tb needed?). Can the data be split into easier to handle chunks?
If it is, then I personally do an initial sneakernet to get the fist set of data over. Then mirror different on a regular basis.
Good post... should be in the Magazine FAQ/Wiki...
Few more scams to call out...
Send money to help family member injured out of town.
Amazon fake order (anyone calling for that matter saying you've been billed or ordered something).
Car should also be for anything requesting a deposit before seeing in person with appropriate access or buying, (rental property, pets...). Usually high pressure and a really good deal situation.
if it's too good to be try or you feel soemthing is off... it usually is.
Two drives is a good thing. Always have a copy at a remote location and swap it out rather than shuttling the one drive back and forth.
rclone is a good solution. I use it myself. I also just found out about syncthing which is great for syncing with your phone to something to the local network.
