Make a bootable backup of your OS X system. Synchronize! Pro X is a professional-strength file synchronization and backup utility for Mac OS X. As a way of introducing you to Synchronize! Pro X, you may use its basic file synchronization and backup features free for folders containing 10MBytes or less. Just download Synchronize! Pro X and try it out. Unlimited use of all features requires the purchase of the program, which is $99.95, plus shipping if applicable. Synchronize! Pro X has many uses. As an example, you can use Synchronize! Pro X to backup your OS X startup disk to another hard disk, so that the backup disk is bootable. You can sync your home folder with a file server, or your PowerBook, or a FireWire disk, so that the files on both are up-to-date. Synchronize! Pro X actions can be scheduled to be performed at night or at any preset time, once or periodically, without anyone present. Passwords can be supplied automatically for file server connections. Warning: Multiple FireWire devices connected to your computer may cause system hangs or possible data loss. Mac OS X has a shortcoming which can cause a suspension of communications with a FireWire hard disk during a backup if more than one FireWire device is connected to the computer.
