When I try and schedule a Windows Server (R2) backup (with the Exchange plug-in) it says "The task XML contains a value which is incorrectly formatted or out of range". I can submit an immediate task without a problem, though.

I did enable the backup feature after Exchange was installed. That's the only thing that I can think of which may be causing this.

SYMPTOMS

 

When you try to change the run as user for a scheduled task in Server 2008, The task is currently configured to runas SYSTEM. Using the following command line he receives the error.

 

c:\>SCHTASKS /CHANGE /TN TestTask /RU TestUser

 

SCHTASKS prompts the user for a password for the runas user account. After entering the password it displays the following error.

 

"ERROR: The task XML contains a value which is incorrectly formatted or out of range. (52,4):Task:"

 

The task's runas credentials have not changed.

 

RESOLUTION

 

To avoid this error you must add the /RP option with an "*". The new command line will look like this:

 

c:\>SCHTASKS /CHANGE /TN TestTask /RU TestUser /RP *

 

SCHTASKS prompts the user for a password for the runas user account. After entering the password the task is updated without error.

Tim,

if i want /ru to be "BUILTIN\Users" it has no password. and even if i used "/rp *" it will bypass my error of " task XML contains a value which is incorrectly formatted or out of range " , and task is getting scheduled but it is not running.  

can you advise for Windows 2012 server pop up same error message while finishing windows server backup wizards,

Thanks

The Windows (R2) built-in tool Windows Server Backup only  supports backup NTFS format, and if you want to do a schdule backup, you have to prepare a separated, dedicated disk to run it. If you can't satisfy those conditions, you won't schedule backup successfully. Thus, you may need some third  party software like AOMEI Backupper Server to help you. It can backup schedule in a few steps.
