Google Base deleting information

Even Google who I always expected to be good at archiving information deletes info as their scope changes. I expect it of Yahoo, but not Google. There was Google Base, and experimental database where you could add all sorts of information including things for sale. The scope has changed and it is now a commerce site. It is now Google Merchant and it appears that all 1,000 biographies I added are gone. The best strategy to manage your digital footprint is store information at a minimum of three sites. I thought Flickr was good but it appears that once you stop your yearly payment the organization of your images are no longer seen by others in sets and organized in chronological order.
