Ouch: the cloud can hurt

Obviously, it's not a problem of having photos deleted from an online service. As best practice would dictate, the photos uploaded to FLICKR shouldn't be the digital originals. But with social and cloud services, it's the url that is of importance. By providing a resource through a cloud service, this resource gets a unique id. Even after uploading (which will take hours) all photos, the ids, that may be linked all over the web, are lost forever.

When using a managed service, think of the possibilities at hand, which service actually may be restored or protected through means of backup. Cloud services, especially shared services, actually set a business value to a non obvious item: the id itself.
