The analogy is paying to have data stored on Amazon S3. It's redundant by default, you can easily migrate it to another storage provider and it doesn't stop you keeping your own local copy.
Bitcoin is strictly better than this option (not factoring in cost) because if you stop paying Amazon S3 the data is gone. If you stop paying your Bitcoin provider there's a very good chance you'll be able to get the data back at a later date. You just shouldn't assume this is garunteed. If you want this garuntee put the data in a spendable output and be prepared to pay a little more in tx fee.
