When you backup the system state and the Exchange Server 2003 information store in the same backup, NTBackup.exe errors with Application event log entry:
Type: Error Source: NTBackup Category: None Event ID: 8019 Description: End Operation: Warnings or errors were encountered. Consult the backup report for more details. OR Type: Error Source: NTBackup Category: None Event ID: 8001 Description: End Backup of 'Servername\Microsoft Information Store\First Storage Group' 'Warnings or errors were encountered.'The backup log contains information similar to:
The 'Microsoft Information Store' returned 'Backup is already active. ' from a call to 'HrESEBackupSetup()' additional data '-' The ' Microsoft Information Store' returned 'Functions called in an invalid sequence. ' from a call to 'HrESEBackupClose()' additional data '-' The operation was ended. Directories: 0 Files: 0 Bytes: 0 Time: 1 secondThis behavior occurs because the Volume Shadow Copy service places Exchange Server 2003 in a 'backup in progress' state, causing the Exchange Server 2003 online backup streaming API to fail to bind to the databases.
To workaround this behavior, back up the system state and the Exchange Server 2003 information store using separate backup .BKF files.
