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).
Open for suggestions.
No hands-on experience with Proxmox or TrueNAS but I do have a idea.
Get Proxmox Backup Server running, point VE storage to the Backup Server. In TrueNAS, open up a share as the destination for the Backup Server, and install wg within
On the remote NUC, install a TrueNAS VM and wg within, then create a backup pool. Connect the two TrueNAS instance together and create a remote sync in TrueNAS.
This setup will gives you 2 backup copies of your data, one local and one remote.
This might work but again I have no experience with Proxmox or TrueNAS. It's just an idea.
