Is there somebody backport the augmentor module?

I'm fairly sure, as there are no issues for that here: 

https://github.com/backdrop-ops/contrib/issues

If you want to request a Backdrop version, you could do that here, but backports from D8+ versions are much harder than ports from D7 version, so you may not get much traction.

It's also not in our list of projects here:

https://backdropcms.org/modules

It may be that a Backdrop version would be easy to backport to D7 but given the definite end of life announced here, it is very unlikely that anyone would be investing time in a D7 version:

I'm guessing, by the fact that you're here on the Backdrop CMS forum, that you have started the journey of considering whether Backdrop is the right destination for your D7 site.  If we can help with anything related to your evaluation and/or upgrade to Backdrop CMS, please feel free to ask here, in our chat channel (https://backdrop.zulipchat.com/#all_messages), or in our weekly Office Hours sessions (see the top of the sidebar for the link)
