[ISS Support Case] Backup of Historian Server

Last updated: March 7th, 2025

Description

We are having a problem with the backup of our Historian server. Other functions of the Historian server are working as expected. The backup vender is recommending the below fix: To troubleshoot the issue please perform the following: - restart following services in this sequence: 1. COM+ Event System. 2. COM+ System Application Service. This may not be started (if not, start it). 3. Distributed Transaction Coordinator Service. 4. Volume Shadow Copy Service. 5. SQL Server VSS Writer. Would restart of any of the above services impact recording of tag data or any of the other main functions of the Historian server?
