Finally, after many months of development and testing, my buddy Jedda has released his excellent backup script called Counterpart. The utility is written in Bash, and is a neat wrapper for rsync 3 to perform an easy backup of OS X.
While Time Machine backups are excellent, especially since OS X Server requires it to do proper backups, there’s nothing better than a bootable clone just in case your system goes down during crunch-time. There’s nothing worse than having a drive fail, only to find it’s going to be another few hours before your system will be live again. That’s where Counterpart comes in.
Check out the article on his blog, or go straight to the code if you’re that way inclined.
And the best part? It’s freeeee.
