DropSpace is an Android application for backing up files on sdcard through Dropbox. Users can choose any files/directories on sdcard to be synced with remote directories on Dropbox. It can start syncing on users' demand, and also can be run as a service that will automatically start with certain time intervals.
When you run the app you're prompted for your Dropbox credentials. After logging in to Dropbox, you get to select which device folders you'd like to sync to the cloud. It's a straightforward mapping process: You select a folder on the device, and then specify where in Dropbox it should go.
The interface is rather clunky, at least for now. The biggest annoyance is that you can't edit your "sync list": if you add a folder and then wish to remove it, you must delete the entire list of folders and start over.
