A System State backup operation is unsuccessful when it tries to back up custom event log nodes in Windows Server 2003

View products that this article applies to.

Symptoms

When you try to back up the System State information on your Microsoft Windows Server 2003-based computer, the backup operation is unsuccessful. The backup operation fails when it tries to back up custom event log nodes that you have created.

Cause

This problem occurs if both the following conditions are true:
  • You back up the System State information by using a backup program that does not support the Windows volume shadow copy functionality.
  • The custom event log nodes have names that are 12 or more characters in length.
When you create a custom event log node, an .evt extension is appended to the name of that node. However, if the node name is more than 8 characters long, the file name extension is truncated so that the complete file name is not more than 12 characters. If the file name is 12 characters or longer, the .evt extension is not added. In this scenario, when the file does not have a file name extension, the backup program considers the file to be a registry hive file and tries to back it up by using a different method than it uses for event log files. Therefore, the backup operation is unsuccessful.

More information

After you install this hotfix, the following changes occur in Windows:
  • When you create a new custom event log node by creating a new registry key under
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\EventLog
    the new log file is created with an .evt file name extension in the %SystemRoot%System32\Config folder. For example, if you create a custom event log named "My Custom Log", the new log file is named, "My Custom Log.evt". On a computer where this hotfix is not installed, the new log file would be named "My Custom Lo".
  • When the Event Log service creates a new event log, the registry value File is correctly created and populated to point to the correct file.
  • If a log file was created before you apply this hotfix, and if that log file already has a File registry value, the Event Log service does not change it. This behavior is by design, because the File value might have been intentionally created as a user preference. Typical event logs always specify the File registry value while the Setup program is running.
  • If a log file was created before you apply this hotfix, and if that log file does not already have a File registry value, a new file with an .evt file name extension is created when you next restart the computer. For example, if you have a custom event log that is named "My Custom Log", and if that custom event log has no File value in the registry, when you restart the computer, the Event Log service leaves the "My Custom Lo" log file on the hard disk and creates a new "My Custom Log.evt" file. In this scenario, the new file is used to log events. However, the earlier events remain in the previous log file in the %SystemRoot%System32\Config folder.
