I am considering a trip around the world and want to keep my data safe, no matter if i get robbed, lose my bags or other unknowns.
I use a macbook, and have a 8tb airport time capsule at home, which has 100mbit connectivity to the internet.
I would like to expose a vpn endpoint from a low power device such as a spare raspberry pi i have lying around, and allow access to a networked apple airport time capsule device which resides in my lan here.
Alternatively, i use an eero wifi router, and maybe? There is a way to expose a vpn or similar on it.
What setups would you recommend software wise to allow my macbook to perform backups via a vpn to the timecapsule?
