This project is an implementation of FTP server in pure Ruby. It features the ability to start a FTP server and publish there any content you want. You are not limited to publish file system subtrees. All FTP hierarchy is dynamic and under your control.
Tartarus provides a nice wrapper around basic Unix tools such as tar, find and curl (well, that's not that basic) to provide a seamless backup solution, aimed at automatic gathering and backup. It has the ability to do full as well as incremental backups
