Series
Three-part series covering the 3-2-1 backup rule for Proxmox Backup Server. Each part covers one tier of redundancy end-to-end: setup, backup, and restore validation. Part 1 covers USB removable datastores for local redundancy. Part 2 covers PBS-to-PBS pull sync for hardware fault tolerance. Part 3 covers Cloudflare R2 for true offsite cloud backup. Each video is standalone but cross-referenced.

Part 1: Tutorial
Start a 3-2-1 backup: pass a USB drive to your Proxmox Backup Server VM, create a removable datastore, and run a real disaster-recovery drill to prove it works.
Part 2: Tutorial
Add hardware redundancy to your backups: stand up a second Proxmox Backup Server that pulls from the primary over an API token, and see why pull beats push.
Part 3: Tutorial
Add the offsite tier to a 3-2-1 backup: sync Proxmox Backup Server to a Cloudflare R2 bucket over S3, with scoped API tokens and group-filtered sync jobs.
