Well, lets face it, there's been pretty much nothing in terms of decent backup solutions for Mac without having to dig in your pockets. Even Apple (at the time this is written) only offer the "Backup" application if you sign up to their .mac account.
Now we love Apple, and the Mac, but we feel that in today's climate of mass media and reducing paper systems, a backup application should be almost standard with every OS. It's true, Apple's OS X does have some very good file manipulation software 'under the hood', but still, its very difficult to access for non-UNIX savy users.
So that is why we've decided to put a significant amount of work now and the future into "Phew", a decent backup app for Mac thats FREE. We hope you find this useful, and if you would like to contribute some small donation to our current and future efforts we'd very much appreciate it. Any bugs/feature requests, please email us.
NOTE: Phew currently doesn't backup the resource portion of files. In short you may find incomplete files on your backups (text clippings for example). This probably won't effect 99% of most peoples data but please check critical files after a backup to make sure. We are working to address this issue.
