How to change the System Logon Account credentials in Backup Exec if the password to the account is unknown.

Problem

How to change the System Logon Account credentials in Backup Exec if the password to the account is unknown.

Cause

  • The user account that is associated with the System Logon Account in Backup Exec may get locked out in Active Directory due to failed logon attempts with the old password
  • Backup jobs will fail due to authentication errors

 

Solution


For various reasons, the credentials stored in the Backup Exec System Logon Account may become unsynchronized from the actual domain or system credentials.  The problems that this can generate include:

 
  • The user account that is associated with the System Logon Account in Backup Exec may get locked out in Active Directory due to failed logon attempts with the old password
  • Backup jobs will fail due to authentication errors
In Backup Exec 2010 R3 and earlier versions, the Logon Accounts can be managed from Network Menu -> Logon Accounts.
For Backup Exec 2012 and later, logon account management  window is available in Configuration and Settings -> Logon Accounts -> Manage logon Accounts.

To change the credentials stored in the Backup Exec System Logon Account, it is necessary to know the stored password.  If the password for the Backup Exec System Logon Account is unknown, no changes can be made to this account.  The System Logon Account will have to be deleted and recreated using the process outlined below.  

The System Logon Account shows up in the Network > Logon Accounts window.  If System Logon Account is missing, click on the button on the right hand side of the window labeled System Account as this account is required to communicate to the Backup Exec services.

Note: The Windows SYSTEM ACCOUNT and the Backup Exec System Logon Account are unrelated entities.  The Windows SYSTEM ACCOUNT is a special user account which does not have user-specified credentials.  The Backup Exec System Logon Account is a logon account that is user-specified during installation and required for proper Backup Exec functionality.  The button labeled System Account does not refer to the Windows account but is short for the Backup Exec System Logon Account.

Use the following steps to resolve the issue if the password on the System Logon Account is unknown:
 
     1. Login to the Backup Exec server using the account which shows as the Owner account for the System Logon Account.

     2. From Logon Account management window, create a New account. (a dummy Example account as given in figure 1).
 
3. Take note if the System Logon Account is the 'Default account', noted by a "Yes" in the Default column.
 
4. Delete the System Logon Account. This account cannot be deleted while it is marked as the 'Default account'.  Select the Example account to be the 'Default account' during these steps.
 
5. If prompted, choose to reassign the backup jobs to the account that was created in step 1.
 
6. Click on the System Account button on the right.  This button is disabled if a System Logon Account exists (Figure 1)
 
7. Assign the correct credentials using DOMAIN\USERNAME format.
 
8. Depending on the setting noted in step 2, select the check box that says This is my default logon account and click Ok.
 
9. Delete the user account created in step 1 and reassign the backup jobs to System Logon Account when prompted.
 

 
Often, the Backup Exec services use the same credentials as stored in the System Logon Account and may also need to be changed.  Use the following steps to change the service credentials:

 
1. In Backup Exec, go to Tools > Backup Exec Services and choose Services Credentials.
 
2. Put a check in Change service account information.
 
3. Enter the updated user credentials.
 
4. Restart the Backup Exec services.
