Backup Exec updates, maintenance releases, and hotfixes can be deployed automatically via the built-in update tool or downloaded manually from the Backup Exec Support Center.

Backup Exec recommends enabling automated update features on your Backup Exec server:

• Backup Exec 20 through 24: Updates are delivered via Veritas Update.
• Backup Exec 25: Updates are delivered via Arctera Update.
• Release Cycle: Maintenance Releases and Hotfixes are published to the automated update service approximately two weeks after their initial release. Prior updates for a specific version are superseded and removed from the feed once a new rollup is released.

If your Backup Exec server lacks Internet access or requires offline patching, follow these manual download and installation steps:

1. Download Product Package: Download the patch or installation package directly from the download center article (100076812: How to Download Backup Exec, DLO, or System Recovery Products) or locate your build file in the Release Updates matrix below.
2. Unblock the ZIP File (Crucial Security Step): Right-click the downloaded .zip file, select Properties, check the Unblock box at the bottom of the General tab, and click Apply / OK. Windows automatically blocks web-downloaded files, which can cause extraction failures or missing DLL errors during setup if left blocked.
3. Extract Archive: Unpack the contents of the unblocked ZIP file into a designated folder on the Backup Exec Media Server.
4. Run Installer: Right-click the installer executable (e.g., Browser.exe or .exe patch binary) and select Run as Administrator to execute setup.

• Upgrade Strategy: Customers are strongly encouraged to maintain their installations on the latest product version to ensure system stability and security.
• Remote Agent Redeployment: Applying an update or patch to the Backup Exec Media Server requires a subsequent redeployment/upgrade of all protected Remote Agents.

• Install (Full Installation Media / ISO): Represents the complete base installation media. Use this package to perform a clean installation or to execute a major version upgrade from one major release generation to another (e.g., upgrading from version 24.0 to 25.1).
• Patch Update (Maintenance Release / Minor Update): Contains cumulative updates and feature enhancements for a specific minor or dot-version release (e.g., updating from version 25.0 to 25.1).
• Hotfix: A targeted patch designed to address specific bug fixes or critical security vulnerabilities for a major or minor version release.
