I know what most will say, I'm not supposed to be connecting to my home servers from my work computer. I get it. I currently use Dex on my Samsung phone to have remote access to my home systems which I connect to my work laptop but run into some bugs here and there. Is there a more efficient way to have encrypted remote connections to my home system? I was considering seeing if I can route VPN traffic through a split tunnel to my home network through a specific interface on my windows laptop that connects to a Hotspot while maintaining LAN connection to my work environment.

I have a synology NAS where I backup my photos to. What would be the most cost effective way to encrypt and back up this data without having to purchase another NAS and install it at a family member's house. It would be about 5 TB and would not touch the data unless my NAS completely takes a crap.
