Fujitsu give you two CD's for recovery, a winblows disk and a driver disk, they don't use a backup partition so there is no sense in looking for a separate partition.
Now, if I am understanding the OP's question properly, "backup and restore" can be added to the machine by going to "Control Panel->Software" and then click on the bit that says something like "Add Windows Components" (my machine is in Dutch, so I doubt it would help if I gave you the path I have here). That will let you install whatever parts of Winblows you feel you are missing, or remove bits you feel are just wasting space.
