This program has a couple of really useful features. It can access the UNIX backup and it can synchronize file changes, renames, deletions and so on. I registered the application, but since then I have found a major flaw. It is incredibly slow on larger jobs. My documents folder is 14GB and takes over 20 minutes to scan and sync. The free application called "SYNC" does this is a couple of minutes. If you want reliable backups, this is a good tool. If you want to get out of the office, look elsewhere or plan accordingly.
