Release Information for Veeam ONE 12 and Updates KB ID: 4705 Product: Published: 2024-12-23 Last Modified: 2026-08-25 Veeam ONE v12 Releases 12.3.0.7165 What's New Veeam ONE 12.3 Patch 1 is a cumulative maintenance and security update for Veeam ONE 12.3. It resolves reported issues across reporting, monitoring, alarms, licensing, and integrations, adds REST API and ServiceNow enhancements, and addresses externally reported security vulnerabilities. Applying this patch is recommended for all Veeam ONE 12.3 deployments. New Features and Improvements Cloud Backup Sizes in the REST API The public REST API now reports the size of cloud backups and of their restore points. AWS Account Identification Veeam ONE now collects the AWS Account ID and account alias for workloads protected by Veeam Backup for AWS, and the public REST API returns both for protected Amazon EC2 workloads. Customizable ServiceNow Short Description Resolved Issues - Veeam ONE repeatedly logs an error because triggered alarms are not synchronized correctly between the alarm cache and the database: Cannot insert the value NULL into column 'triggered_alarm_id' - The Backup Copy RPO alarm reports incorrect information because deleted backup copy workers are still taken into account. - The Backup Job State alarm does not raise a Warning when a backup job session finishes with a warning.
