Error

CExBackup::backupService:HrESEBackupSetup: Error Number 0xc80001f9: Backup is already active.

Cause

The exchange server is busy in the process of being backed up.

Resolution

  1. Check that other backup software is not scheduled to backup exchange on a conflicting time to CyberSecure.
  2. Try the backup again at a later time.
  3. If that still doesn’t work and there is no other software taking an exchange backup, restart the “Microsoft Information Store” exchange service.
