 Default settings for Exchange virtual directories

Based on the above URL’s I’ve following Questions

1. Is there a way to take back up of files & then make changes to virtual directories so that in case of any mess, we can replace those files?
2. Why is the number of Virtual Directories different in different versions of exchange 2013? Refer LAB & Production Snapshots below on same OS, windows server 2012 R2

1. From Above Articles, Brian’s article says we need to reverse SSL Settings on all virtual directories like we do for HTTP Redirect. In MustbeGeek article it doesn’t say anything? In my lab the working set has a mix of both?
2. Please provide one correct URL of blog/technet article of this configuration on Windows server 2012 R2?
3. What is the key difference between Exch 2010 & Exch 2013 redirection?
4. Like Exchange 2010 do we have Exchange 2013 Guides?
