Backing up VM's and LXC's offsite

[bj2277]

Hello everyone,

I hope you're all doing well. I'm planning to set up two Proxmox servers—one at my home and another at a friend's place. I have a mix of VMs and a few LXC containers running on both nodes.

Server 1:

• 256GB Samsung NVMe (OS and some LXC containers)
• 500GB Kingston SATA SSD (for additional VMs and LXC containers)

Server 2:

• Two 256GB SSDs in ZFS (handling all tasks)

My plan is to set up a Proxmox Backup Server as a VM on each node. Each server will back up the other, meaning Server 1 will store backups of Server 2, and vice versa.

I’m still figuring out the best way to implement this and make both servers accessible remotely. To access services within VMs, I currently use Cloudflare Tunnel.

Could someone suggest the best methods for setting up backups between these servers? My data needs are relatively light, as I primarily host websites and applications like Invoice Ninja, OpenVPN, WordPress, Odoo, and a CRM.

If one server goes down, having a backup and a way to restore it to the same server after reinstalling the OS would be critical for me. In the future, I plan to add a 2TB SSD configured with ZFS or Btrfs, so having an offsite backup is important.

Additionally, I’d appreciate any advice on how I could also copy these backups to the cloud for extra peace of mind.

Thanks in advance, and please feel free to correct me if I’m missing something!
