About Synchronize! Pro XA professional-strength file synchronization and back up utility. It makes bootable backups of your Mac OS X system disk and synchronizes files between any two folders. It keeps the newest files in two locations by copying any newer file from one folder over an older version in the other folder. The two locations can be different disks (IDE, FIreWire, or USB) on the same Mac, a desktop Mac and PowerBook, or a Mac at work and a Mac at home.Many more features.
