When you try to back up the Exchange Server 2003 messaging databases and the Windows Server 2003 System State information by using the Windows Backup Utility (NTBackup.exe), you experience the following symptoms:
This issue occurs if your Exchange Server 2003 database files are located on the same drive as the Windows Server 2003 operating system.
This issue occurs because there is a limitation of the NTBackup program. When the Exchange Server 2003 databases are on the system drive, and you perform a System State backup, the Exchange Server 2003 storage group is frozen during the System State backup operation. Because of this, the streaming backup of the Exchange Server 2003 databases cannot start. You cannot perform two simultaneous backups on the same storage group.
To work around this issue, use one of the following methods.
Method 1: Perform Separate Backup OperationsConfigure separate backup operations for the System State and the Exchange Server 2003 databases. After the System State backup is complete, the storage group is unfrozen and may be backed up successfully.
Method 2: Move the Exchange Server 2003 Database FilesMove the Exchange Server 2003 databases to a drive other than the operating system drive. This permits you to back up both the Exchange Server 2003 databases and the System State information at the same time.
When you perform a System State backup operation, you cannot perform a streaming backup of any Exchange Server storage groups that are on the system drive until the System State backup is complete. Additionally, you cannot dismount any databases that are in those storage groups until the System State backup is complete.
The Volume Shadow Copy service for Exchange is disabled in Microsoft Windows Small Business Server 2003. Instead, the NTBackup program uses the Exchange Server 2003 online backup streaming API to back up the Exchange Server 2003 information store. This permits the NTBackup program to back up System State information and the information store at the same time.
