Is there a way to back individual profiles
go to the user data, copy and paste Default or Profile # you want to back up, rename it to something else and done. If you think about ‘backing up’ like using it in another computer or if disk fails or something, then, you should be aware that cookies, passwords and some settings are encrypted, so you will not get to use them for that, for that exporting them to plain text or use sync is the only option.
