Enhance the Restoring a Database From a Backup section

[miyconst]

This section Restoring a Database From a Backup is very generic, and it requires some enhancement with examples and coverage of the common problems, such is invalid configuration files, name mismatch, and similar.

@Mackiovello it has to be done, but no rush, Starcounter.Nova has higher priority.

I think it is good to provide examples include file names and folder names.
