Mini-dump vs full-dump

The difference between a mini-dump and a full-dump is more related to the format of the file than the amount of content/information in it. In fact, with the right configuration, a mini-dump will contain more information than a full-dump ever could and that is why properly configured mini-dumps are recommended in all cases.
