NAS + VPN will get you personal cloud storage under your own control. Set up the NAS, configure the firewall to only allow connections from your home network, VPN, and Docker network while blocking everything else, put your files on it, connect back to your home network via VPN to securely access your files from anywhere on earth. Primo security and privacy, and all of this can be done on the NAS itself.
I use a Synology DS220+, which costs like $300ish. Pick up a couple 10TB hard drives and an 8GB stick of SO-DIMM (laptop) RAM for $20 and you have an entire media server + piracy box + cloud storage + VPN + pihole + DNS + anything your little heart can configure in a form factor roughly the size of a Gamecube
But you could do some media serving. Take back your life from both Google AND all 263 streaming services all at once! You could even self-host a Lemmy or Mastodon instance and take back control from social media giants while you’re at it! Add in NextCloud and self-hosted Bitwarden, and idk what cloud service you could realistically need at that point, and it’s all yours!
Just something to think about, comes highly recommended from me. $4-500 startup cost is like 2-3 times what my broke ass is comfortable with, but I have not regretted my purchases for even 1 single day.
