iRep

  Compare and replicate folder changes across your local network; keep your documents in sync between your laptop and your desktop PC, or use it with almost any portable storage device to backup important folders.

File synchronization using iRep is safe and reliable, since iRep uses Microsoft's Volume Shadow Copy technology to ensure skipped-files-free synchronization. iRep's Safe-Sync feature, on the other hand, backs up all files deleted or replaced during synchronization, to allow users to rollback to previous versions of files.

Flexible file filtering lets you ignore files and/or folders that you don't want to synchronize, and "pre and post events" feature gives you the ability to automatically execute commands before or after synchronizing your files (Check files for viruses, make a compressed copy of the target folder, etc.)

Finally, with unattended automatic synchronization, you can configure iRep to regularly and reliably synchronize your folders even when you're out of town.
