Use a battery in the Vbat pins of the DS1307 RTC... and make sure your code is not going to override the time inside the RTC when you boot up.

Sorry, but I´m using the examples that has the library and it already has a batery , where do I have to verify, if the code canceled the time and date inside the RTC?

As long as you only write the time/date to the RTC under operator control or some other similar event you should be OK.
How DO you set the time/date?
