Backup is a Ruby Gem, written specifically for Ruby on Rails applications. This gem offers a quick and easy way to configure and run backups of your MySQL/PostgreSQL databases (and practically even any other database you can dump through the command line). It can also make backups of your archives (any files or folders). All backups can be transferred to either "Amazon S3" or "any remotely accessible server using the SCP, SFTP or FTP transfer methods". Backup handles: Compression, Archiving, Encryption and Backup Cleaning.
