Well, another upset customer here.
Not only the new modem does not offer the settings backup option, but it does not offer it despite that being the main reason I asked to be sent a new modem and agreed to 6-month contract and a 10 bucks delivery fee. The settings backup option was literaly the reason I wanted that new modem and it must have been clear to the support person who called me regarding my phone not working, wanting to factory-reset the modem remotely in an effort to fix that issue. Since I have so many settings in there that it is a half of my day spent setting everything up again, I said I was not happy to do that and then potentially do that again on a new modem if a replacement was needed and that I'd really like to have a modem that has the backup option available anyway, so would it be possible to send me such a modem please? I was told that yes, with those above mentioned conditions. For the backup feature I was happy to agree to both. And now I have a modem that does all the same things the just replaced one did and no backup option, also same as the original modem. And I found that out after I set everything up. Very upset... ! :-(
