Hot on the heels of pyrobocopy, a message just came up on comp.lang.python.announce:

 1.1. What is dfp?
 =================


A frequent software pattern is processing files that have changed:
- an incremental backup system, which will add new and changed files to
an archive or transfer them to another computer
- a website update with the latest changes
- automatic processing, like compiling changed source code
- software integrity check: detect changed files and raise an alert


dfp is a suite of components which permit to detect changed files and to process them. The components are split into 3 categories: 
detection: dfp 
processing: dfpCopy, dfpTar, dfpZip, dfpFtp, dfpCmd 
updating: dfpUpdate 
dfp works with snapshots, i.e. an image of a situation is initially taken, and on subsequent calls the new situation is compared to the former. This comparison results in files being classified either as different, gone, new, or same. 
A processors may then be used to process some or all of these files; example processors permit to copy files, send them by ftp or put them into an archive. You may write your own processors for any specific need. 

Finally, the snapshot can be updated to reflect the processing, if successful.

I haven't actually investigated his stuff out yet - but the description seems intriguing.
