iRep

iRep is a flexible and user-friendly compare/synchronization tool that can replicate folder changes across your network to synchronize two or more folders at a time.

It comes with 5 built in sync actions: Backup, Mirror, Merge, Distribute and Collect; and allows users to create their own custom sync actions.

Keep your files in sync between your laptop and your desktop PC, synchronize your workgroups' shared folders, or use it with almost any portable storage device to backup important folders.

Other features include: file filtering (by name, size and date), file revisioning, skipped-files-free synchronization, pre and post-sync command execution, quick-sync, and scheduled unattended sync tasks.
