We had some reports about automatic Vault Server backups (via Windows scheduled tasks) that takes several Hours longer after moving the Vault Server to a Windows 2008 Server operating system.
You also noticed that the Performance when backing up through the ADMS console is good.
Background: In Windows 2008 Server Microsoft has changed the behaviour of tasks and there is also a change of the priority of processes in general.
In Windows 2003 Server a scheduled windows task is created with Priority "Normal".
However in Windows 2008 Server the priority of the tasks is 7 which is below normal Priority.
The solution is to make sure that the scheduled windows task is running with a higher Priority.
The priority can not be set to a task directly but there is the following workaround:
1. Go to Start - Control Panel - Administrative Tools - Task Scheduler
2. Find the task which is executing the Vault Server backup
3. On Action Menu go to Export... Save the file as *.xml
4. Open the XML file via Notepad
5. Find the line <Priority>7</Priority>
6. Change the value of the Priority from 7 to a higher Value like 4 or 5
7. Save the XML file
8. Delete the Scheduled task about the Vault Server Backup
9. In the Actions Menu go to "Import Task" and choose your XML File
Your task is running now with a higher priority and it the time that your backup takes should be much lower.
