Simplify backup best practices section

[Jeran-Tek]

Removed redundant sentence about backing up domain controllers. Backing up the FSMO role owners is unnecessary because they can be seized without loss of data. Starting a restored DC with a FSMO role can significantly delay the first boot because of initial synchronisation requirement.
