 \([^"]*\) defines a group of characters, the group is actually the found contents between the two braces (), the braces need to be escaped hence \( and \)

 \1 is the contents of the first group
 There could be several groups defined using multiple sets of brace pairs, they are numbered incrementally and each one can be referenced as \n (e.g. \1, \2, \3 etc) hence the name: backreference.
