If Google were to completely shut down right now, would you lose anything? There’s no doubt that many of use would lose thousands of important contacts, calendars, emails, and more! In fact, many of us would be left digitally crippled, with irreplaceable information suddenly gone.

Of course, nobody is expecting this to happen. Then again, 3 years ago few Sidekick users would say they expected their service to disappear either. Unfortunately, T-Mobile recently confirmed that on May 31st all Sidekick services will, in fact, be shut down. When this occurs, Sidekick users will no longer have access to the cloud-based system that defined their devices. Users will no longer be able to access their contacts, calendars, notes, and more. Of course, T-Mobile will be offering solutions for migrating this data to other devices, so all is not lost. However, the news brings up an important point: Owning your data is crucial!

While this may not have been true 3 years ago, I’d be willing to bet that many Sidekick users have come to expect this news more recently. Gmail users, on the other hand, don’t expect to lose their data at any time. But that is exactly what happened just a few days ago. Thousands of Gmail users woke up to an empty inbox. While their data has since been restored (thanks to Google’s redundant backup system), many were without access to important information for days. A hit like that can have a serious effect on your productivity, especially if you rely on services like these for work.

All this said, I don’t want to say cloud-based services are bad. On the contrary, I believe they can be amazingly useful. What is bad, however, is entrusting them with the only copy of your data, because at that point it’s not really your data! In order to access it, you need to be connected to the cloud. In the event of service downtime, you are without access to your data. If you can’t access something when you want to, do you really own it?

Whether you decide to simply back up the information or sync your data to another source, I highly recommend taking the steps necessary to make a copy of your cloud-based data. Hopefully you’ll never need it, but if you do you’ll be extremely grateful for the offline copy! So what are you waiting for? Choose to own your data!
