re: Best cloud based data storage.

Totally depends on how you plan to use the photos.

If you just want to keep the photos for your personal memories, I use Mediafire and have been happy with them. pbase, flickr, and other choices are around too. There really isn't a huge difference.

If you want to share the pics, Google, Onedrive, Dropbox, and whatever Apple's solution is will help you bore your coworkers to tears.

The best choice for safety is to go with two solution providers, but really one is perfectly sufficient unless the Yellowstone volcano erupts.
