AMETHYST 1.5: Critical error: 'Syslog log,21:0:1:

[John Richard Procter]

This is the backup drive, it was not present when a backup or diskspace
check was done.

• Shutdown the PC via AMETHYST Administrator. (Click on the computer icon, with
  the disconnected plugs below it on the homepage)
• Power the server down.
• Switch on the backup drive.
  Insert the archive drive into the tray and lock it (must be locked). You
  need to power the server off, switch the lock to "ON" and boot the server
  for the BIOS to detect the drive. Please note that the server must be
  powered down when you insert the drive and switch the lock to on.
• Re-Start the server again.
  
• Do a test connection to see if it is picking the drive.
• Do a check available disk space to see if there are space to archive to.

Do an unscheduled backup to test the backup drive after this.
