Thanks for the detailed reply.

So my main NAS is Unraid, and I also have a couple of proxmox boxes. Though I’m less concerned about the proxmox boxes as the main files are on the NAS, and I have a proxmox backup server vm set up on Unraid with regular backups there.

For most of my important files on unraid, I have an external drive that I periodically sync and store in a safe.

I also have access to a VPS with over 1TB of space which I am still figuring out how to best integrate into my backup strategy.

For what I’m asking here, I just want to have a simple solution that I can tuck away and have remote access to and just use syncthing or something to keep it updated.
