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.
