rdup

Tool to generate (incremental) backup file list

rdup is an 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. An example script named rdup-simple is included to show how to implement a simple snapshot-style backup strategy.
