Turn a small PBS node into a repeatable offsite backup target for VMs and containers, then prove restores work.

A backup success flag can hide a broken restore path, so this test proves Proxmox S3 recovery boots and verifies data.

Isolation beats exposure: verify blocked sources, pin DNS, and prove the firewall before you open the container.

A dead node need not mean a dead container; a spare node can take over with a verified restore and Docker check.

A ten-minute host audit can stop VMs from inheriting broken bridges, missing VLAN tags, and open management ports.

A single PBS snapshot captures the whole Home Assistant container, so a failed node does not erase your automations.

The traps that break OCI LXC at 2 a.m. are boring: backups, kernel updates, and storage you can fix in staging.

Stop burning ISOs and re-typing cluster settings; DCM 1.1 turns node onboarding into a repeatable, verified install job.

Fresh Proxmox nodes drift fast; verify updates, storage, bridges, and restores before your first VM inherits the mess.

A dead edge node shouldn't force a manual reinstall. This PBS S3 backup path restores Caddy, DNS, and Nginx LXC containers.

Snapshot-mode backups keep Docker running, but a missing OCI image reference can break restore on another Proxmox node.

The first S3 sync can eat your uplink and your monthly bill before you notice the endpoint was wrong.
