This article outlines the antivirus exclusions that can be created to minimize the impact of antivirus software on Veeam Backup for Microsoft 365's performance. These exclusions can be applied to both the built-in Windows antivirus and third-party antivirus software.
Note: Antivirus software will not always cause Veeam Backup for Microsoft 365 functions to fail; it may also negatively impact performance.
Given the complex nature of antivirus software, additional exclusions may be necessary. Users should review their antivirus logs or history to determine if more objects must be excluded.
Although these exclusions are primarily intended for antivirus software, they may also need to be applied to other security software. This includes any software that performs file scanning or access control, which could block or interfere with Veeam-related processes.
All folder paths listed in this article include recursively all files and subfolders.
For folder paths containing Veeam executables (e.g., C:\Program Files\), some security software may require explicit process exclusions to be configured for the executables within those folders rather than a folder-wide process exclusion.
