backmon monitors backup files inside filesystems and object storages. Each backup file definition can be exported into a Prometheus-compatible format. You can use tools like Alertmanager to notify the SRE team if a backup is missing or some threshold has been missed. A threshold could be e.g. that the filesize of the backup file is too small.


The goals of backmon are:

  • Monitoring and supervising existing backup files: inspecting, overseeing, handling, controlling
  • Overseeing backup processes
  • Collecting metric data about backup files


  • Export Prometheus metrics
  • Purging outdated backup files (erase, remove, delete)
  • Centralized download of backup files
