I have a problem in scheduled task for windows server 2003 R2 standard SP 2. The schedule task runs fine when the user is logged in but when is user is not logged in it runs partially. Ex if the file is of 900 Mb it will take backup of 15Mb sometime or 600Mb but never full 900Mb. Everytime the backup size varies. Any help will be appreciated, its urgent. This works fine when the user is logged in.reply at email@example.com.
