I only briefly see the 1st part ("Personal Server"). But since it involve using PGP and setting server where you access it with .onion rather than plain IP address, average people would find it challenging.
It's truly challenging for normal users.
I watched some videos of Andreas Antonopoulos in which he advised that people should never complicate their back up methods too much because it can result in more complex recovery procedure. In worst case, if recovery procedure is broken in the middle by broken piece of initial back ups, the wallet will be lost forever.
Brute force a Bitcoin private key or wallet is almost impossible and the bottom line is keep your back up simple.
