Altaro Backup Check Reference

The Altaro Backup check runs on the octoja agent installed on the backup server and reads Altaro VM Backup / Hornetsecurity VM Backup results from the Windows Application event log. It classifies the most recent backup, restore-verification, and offsite-copy events within a lookback window.

Notes

  • The check recognises the Altaro VM Backup, Altaro Hyper-V Backup, and Hornetsecurity VM Backup event sources, so it keeps working after the Altaro-to-Hornetsecurity rename.
  • Backups must write their results to the Windows Application event log for the check to read them.
