where did you get that from.... and what operating system are you using.


Where ever it came from it is not the way to go to back up and restore the system state.
Backup (Ntbackup.exe) does allow you to restore to an alternate location, but it does not restore the "system state" in a form that will return the system to a working condition. This is because of the way the system state is collected and then processed later during the restore operation.

Maybe if you slow down a bit and follow the proper proceedures.
