CertiStack and the Backup That Has to Prove Itself
A proposed recovery-validation engine for Proxmox Backup Server that boots isolated backup copies, probes their services, and produces signed evidence.
Field notes
The proposed workflow validates more than whether a virtual machine can boot: it checks hypervisor state, a network health endpoint, guest-agent service status, and a console image before tearing the test environment down. The illustrative log reports a 34.1-second run and names the cleanup sequence, including VM destruction, COW-delta removal, loopback unmapping, and SDN-zone purging. The page also specifies Ed25519-sealed HTML and canonical JSON evidence for audits or cyber-insurance documentation.
