If you’re looking for dead simple and secure file synchronization for your Android phone, BotSync links your phone to a remote FTP directory. Stop worrying about filling up your Dropbox quota and start syncing from your own server.
BotSync synchronizes the directories you’ve selected at a set interval against the same directories on your FTP server. The connection is secured via SSH and even if you have a modest FTP account you’ll still have several times the storage of even a premium Dropbox or other cloud-based storage account. Visit the link below to check out the app at AppBrain, BotSync requires Android 2.1 or higher.
