The backup methods are very different for each Google service. If you want daily backups of all your Google services, you need to pay for multiple external backup services and/or spend a lot of time doing it manually.

And how do you download all your Google Analytics data? This page on the Data Liberation page suggests that you export to XML, Excel or TSV. http://www.dataliberation.org/google/analytics But to do daily backups of all the dimensions, metrics, advanced segments etc. would be very time consuming. You could do it easier with the API, but that requires programming knowledge.
