Backup Exec installation notes

The following notes provide information about installing Backup Exec::

  • When you use Windows 2008 or Windows 2008 R2 to host Backup Exec or Agent for Windows, ensure that the following Hotfix is installed:

    • For Windows 2008 - KB4474419 Hotfix

    • For Windows 2008 R2 - KB3033929 Hotfix

  • Before you install or upgrade Backup Exec, review the Backup Exec Software Compatibility List (SCL) and Hardware Compatibility List (HCL) to ensure that your systems are compatible with the new version of Backup Exec.

  • Backup Exec supports the Backup Exec server installation on supported 64-bit operating systems only. Installation of Backup Exec on 32-bit operating systems is no longer supported. However, you can install the Agent for Windows on 32-bit operating systems.

  • The Backup Exec installation program now uses the Microsoft .NET Framework version 4.8. Not all versions of Windows support .NET Framework 4.8. If the Backup Exec installation program encounters an operating system that requires a different version of the .NET Framework, Backup Exec blocks the installation and displays an error message that instructs you to install the required version of .NET Framework.

  • If installation fails due to a SQL Express installation error, refer to the Microsoft SQL Server 2014 SP3 Express Edition readme:

  • An error (error code 2) may occur when you install SQL Express in an environment with the following conditions:

    • Active Directory is installed on a computer that runs Windows Server 2008.

    • The computer belongs to a root domain that uses a short domain name such as "".

      To avoid this error, install SQL Express to a child domain such as "", or use an instance of SQL Server instead of SQL Express.

  • If the SQL Server instance is on the same server that you install Backup Exec on, the service account for the instance must have full permissions to the destination folder where Backup Exec is installed.

  • If you perform a remote install or push-install, and you specify a domain administrator account for the Backup Exec Services, you must enter an existing domain administrator account. New accounts are not granted proper rights for domains. If you perform a local installation, you can specify a new local administrator account and the account is granted proper rights when it is created.

  • When you install Backup Exec, or when you install tape device drivers from Backup Exec, a Microsoft message may appear that indicates one of the following:

    • The software that you are about to install does not contain a Microsoft digital signature.

    • Windows can't verify the publisher of this driver software.

    • The software has not passed Windows Logo testing.

      It is recommended that you allow the driver software to continue being installed.

      To prevent this message from appearing, you can change the policy setting. However, if you change the policy setting to "silently succeed", other driver software can be installed without any warning.

  • The user-created folders that are in the Backup Exec installation folder or subfolders are deleted when you uninstall Backup Exec. If you want to keep the folders, copy them to another location before you uninstall Backup Exec.

The following notes provide information for Backup Exec upgrades:

  • You cannot upgrade a Backup Exec server that runs on a 32-bit operating system to Backup Exec. Migrate Backup Exec to a 64-bit operating system, and then upgrade to the latest version of Backup Exec.

  • The Back up files and directories by following junction points and mount points option is not selected by default. However, the jobs that are migrated keep the option that was selected in the previous version.

  • When you upgrade the central administration server, any managed Backup Exec servers that are not also upgraded may show that there is no available space. If there is available space on the managed Backup Exec server, the backup operation runs. After you upgrade the managed Backup Exec server, the correct amount of available space appears.

  • The Resource Selection column in the server details view on the Backup and Restore tab may display "unknown" if the selections are not available from the previous version of Backup Exec. The first time you run the backup job, the selections display in the Resource Selection column.

  • When you upgrade to Backup Exec, the default cataloging option might change to Enable Instant GRT depending on your Backup Exec server environment and the version from which you are upgrading. After upgrade if this option is not set as the default, you can set the Enable Instant GRT option as the default option to take advantage of faster backups.
