Google wants to mirror and index every byte of your hard drive, relegating your PC to a "cache", notes on a company PowerPoint presentation reveal.
The file accompanied part of Google's analyst day last week. Google has since withdrawn the file, telling the BBC that the information was not intended for publication.
The justification for this enormous data grab is that Google would be able to restore your data after a catastrophic system failure.
Perhaps it's Google's gift to the US government. In August 2003, Admiral John M Poindexter was forced to resign after his 'Total Information Awareness' data mining program was revealed to be indexing "everyday transactions as credit card purchases, travel reservations and e-mail."
Sure, every person and company will happily transfer all their data to Google. Even if they plan to protect the data by encrypting it, there could be still a backdoor.
