Deleting the whole account is really unjustifiable! If OP was abusing some service of Google, then ban him from this specific service, but why take his whole data?
If there is something to learn, it's to keep a local copy of anything you have, and never be 100% depending on an online service. But then this obliterates the benefits of investing entirely in so called cloud services with any company, including Google. Ownership of your data, doesn't seem to be one of those benefits.
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.
