rdup
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.

> find . -type f -newer .lastbackup
what this doesn't take into account is removed files, rdup
does show files that are removed since the last run.

How is this different from find?
Hi there,
I'm curious how 'rdup' is different from the 'find' command, which can trivially print out a list of files modified since the date on some arbitrary timestamp file:
find . -type f -newer .lastbackup -print
You simply 'touch .lastbackup' whenever you successfully complete your backup. The description for rdup makes it sound like it's doing pretty much the same thing...but some of the comments on the different releases imply that it actually has some additional features. Maybe just the description needs updating?
