Carbonite, one of the myriad cloud backup storage services for consumers and small businesses, is testing a new offering called Currents that keeps files synchronized across multiple devices and locations.
You can think of the new service as a central repository for documents, folders, and other files that you might need to access from different devices (smartphones, tablets, or personal computers) or that you might need to share with a team of people who need to revise or collaborate on a project or presentation.
Currents would essentially be a replacement for using a service in which you have to create special folders to share things or for emailing files around and using email inboxes and folders for manual version control.
With Currents, the files are automatically updated as changes are made through either edits or an in-application commenting system (if you choose to share them with other people).
While this in itself isn't all that new or revolutionary, Currents offers a versioning feature that allows you to revert back to an earlier draft if necessary. That's not something that's all that common, which is one of the dangers of using a cloud storage or file-sharing service--they really weren't intended for version control.
The public beta version of Currents can be downloaded for free. The mobile application is available either on Apple iOS or for Android devices.
