Be careful of large data sets
This does not happen very often but if you have large sets of data that can generate hundreds or thousands of files, then be careful selecting those reporting options unless you are prepared allow SnapShot! to process for several hours.
Think of anything that will generate individual files such as User Security Privileges. This will generate one file per user and if you have 10,000 users, you get 10,000 report files. Such documentation, in most cases, is not required in every instance, but can be useful in certain situation.
Similarly, the Email Configuration report will generate excessively large worksheets, depending upon the number of mailboxes encountered. It will produce the reports, but the Excel worksheets will be huge.
Again, it is all about knowing what you need to document and knowing which boxes to check.
