There are plenty of big-name sync tools available for Android -- like Dropbox, SugarSync, and Fiabee. Those of you who prefer taking the DIY approach, however, might want to check out BotSync, a new app that can connect to your own SFTP server.
Configuring BotSync is simple enough. Enter your server address and credentials, the appropriate port number, local and remote directories to use as your base sync folders, and specify the interval at which you want to check for new files. When new files are found, they're automatically transferred.
BotSync is totally free and you can find it in the Android Market -- hit the download link below or take the jump to scan the QR Code.
