Deleting a managed Backup Exec server from a CAS environment

Last published : Apr 02, 2026
If communications are still active between the managed Backup Exec server and the central administration server, you can remove a managed Backup Exec server by deleting it from the Storage tab. When you delete a managed Backup Exec server from the Storage tab, the server is changed to a standalone Backup Exec server. After the managed Backup Exec server is removed from the CAS environment, it still remains on the list of servers on the Backup and Restore tab, so it can still be backed up and restored as a standalone server.
Note: If the central administration server experiences a disaster, communications are lost between the managed Backup Exec server and the central administration server and the managed Backup Exec server cannot be deleted from theStoragetab. However, you can change the managed Backup Exec server to a standalone Backup Exec server by using the Windows Change Program feature.
See Disaster recovery in CAS.
To delete a managed Backup Exec server from a CAS environment
  1. If the storage devices on the managed Backup Exec server that you want to delete are shared with other managed Backup Exec servers, on the Storage tab, right-click the device, and then click Share. Uncheck the servers that share the device.
You must remove the sharing reference to avoid overwriting the media.
Note: If any devices are shared by Fibre Channel SAN, disconnect the devices that are on the managed Backup Exec server before you delete it.
  1. On the central administration server's Storage tab, right-click the managed Backup Exec server that you want to delete from the CAS environment and convert to a standalone Backup Exec server.
  2. Select Delete.
  3. Click Yes to confirm that you want to convert the server to a standalone Backup Exec server.
  4. After you receive an alert on the central administration server that confirms the server was deleted, restart the server that was changed to a standalone Backup Exec server.
    Note: If Backup Exec is unable to complete the request, you can choose to remove the reference to the managed Backup Exec server from the central administration server's database. Then, when the managed Backup Exec server is brought online again, Backup Exec automatically adds the managed Backup Exec server back to the central administration server's database. At that time, you can perform this procedure again.
