The OS is installed on the disks, so you must have them present. Just be sure you are really doing an OS re-install, not a factory default. The former does not erase your data, the latter does.
Of course, something can always go wrong (and not just because you are doing a re-install), so you really need a backup.

Note that an OS reinstall will change the admin password back to the factory default value (which depends on the NAS model). It will also reset the NAS to use DHCP.
It will solve some "root problems" but not others. In particular if the root partition is nearly full, it is a very bad idea to run the OS reinstall.
