Veeam’s malware detection feature scans backups for potential threats before they are restored or used in production. Once a scan completes, the metadata should be published to the Veeam Guest Catalog Service, which stores backup indexing and security scan results.
When this process fails, users may see the “Failed to publish malware detection metadata to the catalog” warning in their job logs.
This warning may occur due to:
- Veeam Guest Catalog Service Issues – If the service is not running or has become unresponsive, metadata may fail to publish.
- File Permission Problems – If the catalog storage location has incorrect permissions, metadata publication may be blocked.
Steps to Resolve the Issue
Restart the Veeam Guest Catalog Service
Simply restarting this service may help resolve the issue.
To restart it:
- Open Services.msc on the Veeam Backup Server.
- Locate Veeam Guest Catalog Service.
- Right-click and select Restart.
Check File Permissions on the Catalog Folder
Ensure that the Veeam Backup Service account has full control over:
C:\ProgramData\Veeam\Backup\Catalog
C:\Program Files\Veeam\Backup and Replication\Catalog
While this issue is not severe, it can still be a concern for administrators who prioritize security and rely on Veeam’s malware scanning. If the issue persists, please contact our support team at support@managecast.com for further investigation.
