A friend of mine was running windows 2008 R2 without Searvise pack 1, when he decided to run the service pack 2 one of his test Veeam Backups servers he got an error message.
To solve this nuisance problem follow the following steps:
- Be sure there are now active Veeam Backup jobs. But I think that’s not the case during maintenance windows.
- Open a command prompt and start DISKPART.
- Enable the automount feature via: automount enable.
- Restart the Veeam Backup server.
- Install Windows 2008 R2 Service Pack 1.
- Restart the Veeam Backup server.
- Open a command prompt and start DISKPART.
- Disable the automount feature via: automount disable
- Restart the Veeam Backup server.
This will solve the problem if you follow the steps correctly.
