WORKAROUND:
Force NetBackup to use BackupRead() API by performing the following changes: (This will not work if you are using Flashbackup to backup the data)

1. Click Start | Run, type regedit, and click OK


Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.


2. Browse to HKEY_LOCAL_MACHINE\Software\VERITAS\NetBackup\CurrentVersion\Config

3. In the Config registry key, create a new key called NTIO

4. In the NTIO registry key, create a REG_DWORD value, give it the name UseNTIO, and the value 0 (zero)
