A backup is proven only by an isolated restore. Preserve the domain definition and every external dependency needed to reconstruct the guest.
Recovery set
- Inactive domain XML and UUID.
- Disk data and verified backing-chain ownership.
- NVRAM, TPM state, secrets, and firmware dependencies.
- Network definitions or an explicit remapping plan.
- Application-consistency evidence and restore instructions.
Isolated test
Restore under a new name and UUID on an isolated network. Do not attach a recovered clone to production identity, shared disks, or the original IP space until collision controls are in place.
BASH
qemu-img check /restore/guest01.qcow2
virt-xml-validate /restore/guest01.xml domain
virsh define /restore/guest01-test.xml
virsh start guest01-restore-testRecord achieved recovery point, time to boot, application integrity checks, and cleanup evidence. Compare those measurements to the stated RPO and RTO.
