Hardware compression mode is turned off when you back up data to a tape drive on a Windows 2000-based computer by using NTBackup.exe (827475)

SYMPTOMSWhen you use NTBackup.exe to back up your data to a tape drive, hardware compression is turned off even when you turn on the hardware compression mode. This problem occurs even if the tape drive supports the hardware compression mode.CAUSE This problem occurs when NTBackup.exe starts to write data to the tape drive. By default, NTBackup.exe turns off the hardware compression mode on the tape drive even if the tape drive supports hardware compression. When NTBackup.exe writes data to the tape drive, NTBackup.exe temporarily toggles the hardware compression mode on or off depending on the compression mode setting. However, when NTBackup.exe finishes the current backup, the hardware compression mode is not restored to its original setting. Later, when a third-party program tries to write data to the tape drive, the data is written to the tape drive without hardware compression.RESOLUTIONMicrosoft Windows 2000Hotfix informationA supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes.
