Today I find acessing deco configuration througth the webpage, and finally saw the option to backup router settings to a file. I'm currently on 1.5.0 firmware version on my Deco S7. Best regards.

@Riley_S Hi, I understand all points. For example, I am waiting a update to Deco S7 V1 ( released last year ), because it has less functions than my Deco M4 V4 ( like vpn options or set MTU size)....

@Riley_S I'm afraid that Tp-link does not release this update for the new DECO S7. Even this been a new release, it lacks this new features.
