CINTRA  This is a great little timesaver.. when iDisk 'gave up' after 2 days of uploading my iTunes Music, I used arRsync to copy the iTunes folder to a 16GB Flash Voyager. It (2.5GB) took almost no time!

Needless to say I use it to sync a number of other items. There should be a donate button somewhere for this 'must have'..

OMWAT  Good stuff sir.

LOMOVOGT  Despite the pre-release status, I rely on arRsync for my daily backups. It is fast, reliable und easy to use. I do not need more features.

ANALOG KID  Simple and free. That it uses the rsync utility within OS X and doesn't re-invent the wheel is smart. It doesn't provide access to all of rsync's functions, but as a pre-1.0 release, arRsync provides the basics to do easy push-button back-ups of your User folder to a second hard disk; something every Mac owner should be doing.

I would like to see a user manual added to explain what the available options do.

CLENT  As useful as a backup solution between hard drives may be for some people. This is a very crippled cocoa wrapper for rsync if you can't specify a remote host.
