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.

Silent S3 upload gaps leave backups incomplete until a restore fails. Discover how PBS 4.2 catches them automatically.

MinIO in an unprivileged LXC container gives PBS 4.2 a self-hosted S3 backend in under 30 minutes — no cloud account required.

PBS 4.2 syncs backup chunks to B2, Wasabi, or R2 for $6/TB offsite retention — no second PBS machine needed.
