Previously using 2 synology devices - one at my home location for NAS duties and another at a remote location for an off-site backup destination. I had a small army of nucs doing various hosting things. This worked well. But as many who self host can appreciate - just because it works doesn't mean you can't burn it all down and try something else. That's where I am. I'm now running everything on a dell r720 server running proxmox and truenas. I have a nuc at the destination with proxmox hosting a VM of windows and Ubuntu. I would like to mostly recreate the back up solution of the synology - which is basic incremental file backups on a schedule with or without versioning. And ideally I'd like to run this through a wireguard (or similar) tunnel to avoid opening up too many ports at the destination.
I've tried some things but can get anything to reliably work (or work at all).
