Systemd Integration: - New 'dbbackup install' command creates service/timer units - Supports single-database and cluster backup modes - Automatic dbbackup user/group creation with proper permissions - Hardened service units with security features - Template units with configurable OnCalendar schedules - 'dbbackup uninstall' for clean removal Prometheus Metrics: - 'dbbackup metrics export' for textfile collector format - 'dbbackup metrics serve' runs HTTP exporter on port 9399 - Metrics: last_success_timestamp, rpo_seconds, backup_total, etc. - Integration with node_exporter textfile collector - --with-metrics flag during install Technical: - Systemd templates embedded with //go:embed - Service units include ReadWritePaths, OOMScoreAdjust - Metrics exporter caches with 30s TTL - Graceful shutdown on SIGTERM
