Changing NTIO value in the Windows registry need a Reboot ??

This issue has been solved. See solution.

Hello all,

On the Windows 2008 NetBackup Client, disable the Symantec API called NTIO.  This will cause NetBackup to use the Microsoft API called 'BackupRead' - which does not encounter the same timing error.


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

2. Browse toHKEY_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 valuedecimal  0 (zero)

Does this needs a reboot , Please advise.

No need to reboot server.

Restart the NetBackup Client Service so these changes can take effect

Hi Manish,

Only NetBackup Client Services to be restarted is that enough else MASTER and MEDIA also needed ??

Altho' I know you've already found it yourself (wink), just for completeness on the discussion as a whole, looks like this one:

You can restart netbackup client service.

Changing registry values does NOT require a reboot, they are "applied" immediately
