Backup

Proxmox has a built-in notification system, but by default it only routes alerts to a local email address. I wanted backup failure alerts delivered to my phone as push notifications – without relying on email. This post covers how I set that up using Gotify hosted on PikaPods, wired into Proxmox’s notification targets and matchers.

For a while, my Proxmox Backup Server (PBS) ran on a dedicated bare-metal machine – reliable, but one more box humming away on the shelf. As part of a broader effort to consolidate my homelab, I decided to move PBS into a VM on one of my existing Proxmox nodes. The catch: I still wanted my local Unraid NAS to serve as the primary backup datastore, which isn’t something PBS supports out of the box. And on top of that, I wanted a second copy synced offsite to a second Unraid server at a different location for a proper offsite backup tier.

This post covers how I pulled all of that off – from the VM setup, through the NFS datastore configuration, to the offsite sync job running automatically.
