Full backup gets all the data and pages. Differential backup only gets the pages that have changed since previous full backup. Ultra-simplified explanation. To get more in-depth information on all things backups check out Paul Randal's blog:

Copy only backup lets you take a backup without affecting your your normal backup sequence and restore procedure.

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
