The hand-managed Linux VMs (not in Terraform) were never imaged: the
PVC/NFS/pfSense/PVE-config scripts cover cluster data but no VM disk. A lost
devvm disk = unrecoverable home dirs + local-only git repos (monorepo root has
no remote).
vzdump-vms.{sh,service,timer}: daily 01:00 live `vzdump --mode snapshot` of
VZDUMP_VMIDS (default 102=devvm) -> /mnt/backup/vzdump (Copy 2), keep 3; the
monthly offsite-sync full pass mirrors it to Synology (Copy 3). Guest agent
enabled -> fs-consistent. Nice/idle-ionice so it never starves etcd.
Pushgateway job vzdump-backup.
Deployed live to PVE + timer enabled. Docs updated: backup-dr.md (new VM-image
layer + protection matrix), infra CLAUDE.md, AGENTS.md.
