Overview

Veeam has released Veeam Agent for Microsoft Windows v13, aligning all Veeam product versions under a unified versioning model (Veeam Backup & Replication 13, Agents 13, etc.).

Why Upgrade to v13?

Performance Improvements

How to Upgrade to v13

Step 1 – Check for Update Inside the Agent

1. Open Veeam Agent for Microsoft Windows

2. Go to Settings (☰ menu) → About

3. If available, you will see a notification that version 13 is available

4. Click Download

Step 2 – Install Prerequisites (If Prompted)

During installation, you may see a prerequisite warning indicating that .NET 8 components are required:

• Microsoft ASP.NET Core 8.0.21 Shared Framework

• Microsoft .NET Desktop Runtime 8.0.21

Click OK to proceed.

The installer will automatically install the required .NET components.

Step 3 – Reboot (CRITICAL)

⚠️ Important: For Windows-based machines, a reboot is required after installing Agent v13 for the updated Changed Block Tracking (CBT) driver.

Failure to reboot may result in backup inconsistencies or CBT not functioning correctly.

Please schedule downtime and reboot immediately after installation.
