You must be running as the local computer administrator to save the backup file in the %Windir%\System32\Wbem\Repository folder. Otherwise, you can save it in the Documents folder for the account profile.
When you click Back Up Now to back up the repository manually, you can back up to a specified file name, and later restore from that saved file.
