Purpose

This article documents antivirus exclusions that may be created to reduce the impact that antivirus software has on the functionality of Veeam Backup for Microsoft 365. These antivirus exclusions may be applied to the Windows built-in antivirus or third-party antivirus software.

Note: Antivirus will not always cause Veeam Backup for Microsoft 365 functions to fail; antivirus software may also negatively impact performance.

Limitations and Considerations

Given the complex nature of antivirus software, it may be necessary to add additional exclusions. Users are encouraged to 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 potentially 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.
