Step 1. Download and Extract Executable File
Download and extract the executable file for update installation:

- Extract the executable file from the downloaded archive.
- Save the extracted file locally on the backup server where you plan to install the update, or place it in a network shared folder.
Alternatively, you can get the update/patch executable file from the Updates folder on the downloaded ISO image.
To install the Veeam Backup & Replication update on the backup server, use the following command syntax:
