- backup role emits last-success/run metrics into node_exporter's textfile collector - node_exporter enables systemd and textfile collectors - prometheus deploys BackupStale/BackupTimerSilent/SystemdUnitFailed alert rules - grafana gains Backups - Restic and Systemd dashboards - fix prometheus.yml params rendering (quote values so {job=...} stays a string)
