So I have a NUC with Proxmox as the primary OS and OPNsense in a VM for my home network. I’ve been trying to move away from Google services but would still like to use them as a back up solution. Would it make sense to use Nextcloud in a VM as a replacement and use Rclone to encrypt and backup my files to Google Drive? Or should I use a NAS OS like Open Media Vault instead?
I’ll also mention that I have an empty SSD that I can passthrough and that my primary draw to Nextcloud is that they have a Windows desktop syncing app like Google Drive does which makes things familiar and convenient. I don’t plan on having my Nextcloud instance exposed to the web but might setup a Wireguard tunnel into the local network in the future.
I've had a lot of good luck with Syncthing. If you're just syncing files locally you can disable nat traversal.
I ultimately did go with Syncthing and uploading my files encrypted to Google Drive for backup. It's been working great for months. I've also been using Zeroteir to make this work with my laptop too while on the go.
