rdup is a utility inspired by rsync and the Plan9 way of doing backups. rdup itself does not backup anything; it only prints a list of the names of files that have changed since the last backup. It also handles files that are removed, allowing for correct incremental backups. Auxilary script that implement a backup strategy are included. License: GNU General Public License v3 Changes: The license was changed to GPL3. Some code cleanups were made, and rdup-simple can now make hourly backups.
