Compare

Compare & Backup is an easy to use and powerful tool for directory synchronization. It allows you to compare source with destination before backup. Compare results are shown in 5 sections:
1) Newer than destination
2) Older than destination
3) Can not find destination
4) Can not find source
5) Only size changed

So you will exactly know what the difference is between source and destination. And you will know which files need to be backuped, which files need to be restored, which files need to be deleted. Compare & Backup can do all those operations for you.
