I love this program. I have been using the trial on and off for a long time, but recently purchased it for work. The fact that it will back up the running configs automatically at night for me alone is worth it. The part I like the most is that when it senses a change in the running config it will copy the old running config into a separate folder and backup the new config. Then it will email me when it has finished and include a zip file with all the changes per config lined up side by side so I can see exactly what has been changed. This is a great feature just in case you had a rogue admin go around and make changes you didn’t approve of. You just simply open up the HTML change file for Router A and you will see the highlighted changes between the old and new running config.
