// in which one path represent the source and other
// represents the target
Path source = Paths.get("D:\\books\\java\\CopyAndMove.txt");

// In order to take a backup we usually use copy()
// method of Files class by passing three parameters
// such as source from where it picks the file
// the target where it tranfers the file and
// lastly the CopyOption which tells that
// whether to replace existing file if it exists
// by the name provided already.

// In order to move a file completely we usually
// use move() method of Files class by passing
