I'm trying to set up a good home data backup solution and am having trouble finding software that would allow me to:

1) Have 2 identical external hard drives. 1 master and 1 slave.
2) Use the master actively to save, modify and delete files.
3) Be able to plug in the slave and run some software that syncs all changes from the master to the slave since the last sync.

Basically create a sort of asynchronous USB raid 1. I'm running OSX 10.8

Are you looking for an Off The Shelf solution ? Or are you comfortable in rolling your own solution ? Rsync would work nicely in this situation. –  Lawrence Feb 11 at 4:23
    
@Lawrence I'm comfortable with the command line, though a simple gui app with a sync button would be nice. –  greg Feb 11 at 22:06

If you're comfortable with terminal, just get rsync and setup your script. There are also several GUI apps based on rsync

I read up on rsync and then did a little searching. What do you think about this answer?: serverfault.com/questions/25329/… –  greg Feb 11 at 22:09
    
Yes! If you're OK with terminal, that should be the best way to do it –  Martheen Cahya Paulo Feb 12 at 4:15
