As for the Photos tab which remained disabled on Sunday, Dropbox had this to say about the particular situation. “We’re continuing to make a lot of progress restoring full service to all users, and are doing so in careful steps.” As you know, there is no fool-proof system in this world, and so for cloud-based services, service outages and probes by cyberattackers happen to be a major cause of concern. Dropbox does save a history of all deleted and earlier versions of files for 30 days for all of their accounts, as this service relies on Amazon’s S3 (Simple Storage Service) in order to capture encrypted versions of people’s files. With a whopping 200 million users worldwide, Dropbox will definitely need to make sure that their security remains up to standard.
