The difference between image and clone is both simple and confusing, because the terms are used interchangeably to mean different things.
Image and clone are two very confusing backup terms.
One reason is a deep, dark, dirty little secret of the industry: we don’t all agree on what these two terms mean. Quite literally, one person’s clone is another person’s image, and vice versa.
It gets confusing, and if you’re hearing different things from different people, that’s why.
I’ll provide what I believe are the most accurate and common definitions. Hopefully, that means you’re more likely to hear people agree than disagree with what I’m saying.

Link-shortening services make it hard to tell a link’s final destination. When you receive one in an email, you may want to do some detective work to see where it’s going – before you click.
Some services do have preview features. For example, if you visit tinyurl.com/preview.php, TinyURL will help you turn on a cookie-based feature in your browser. Then, when you click on a link, you can preview where it goes prior to going there.
Bit.ly also allows you to do this. Simply add a plus sign to the end of the URL, and Bit.ly will display where you would have gone rather than taking you there.
There are also several sites that show you where a shortened link will take you. Some current services include:
Each of these display the target and some additional information about a short URL.
The bottom line, really, is to stay away from mysterious links sent to you through spam. But when you receive a shortened link from a trusted source and you aren’t sure why, investigate with these preview tools.
