How is that different from /exporting the configuration and git it ?
Then compare different commits?
Cause the video on their homepage just looks like it.
The difference is you don't have to do it all by yourself.
You would have to script config retrieval, handle all the edgecases and have proper error-handling, and for a network of any large-scale, you scripts will not scale easily.
Then you would have to do git hooks and other funky things to ignore all the dynamic stuff, and figure out if there was actually a change to the config.
Not to mention, to get change notifications, you would have to write something yourself again that generates graphical diffs out of GIT and renders them to HTML / notification of choice.
The point of config change notifications is that it's a notification.
If you have to watch GIT every day/hour to see if anything in your network changed... that defeats the point.
Not to mention it's just about impossible when we are talking about hundreds or thousands of routers.
All of this is doable by yourself if you want.
It will however cost you a bunch of time.
As with everything, it is up to you if you want to spend your time, or buy a solution (like Unimus, or another NCM system) that already works out-of-the-box.
But a proper NCM system does much more than just backups - you can automate RouterOS upgrades, or any other config push across network, config auditing, etc.
This topic should really not be used for this discussion.
We should keep the discussion here on Vault 7
