No, you don't need to backup the system files of your SQL Server
installation.
In case you experience a problem and can't start your SQL Server services,
you have two options:
1) Uninstall the current installation and install a new SQL Server instance
with the same instance name
2) Install another SQL Server instance with a different name (as you can't
have two instances on the same system with the same names) and redirect your
users to the new instance.
After performing emergency 1 or 2 then you can restore your system and user
databases.
