I have three hard drives full of backups, and I want to merge them into one, bigger hard drive. However, these three drives have many of the same files, yet with different time stamps.

How can I move only the newest files to the new drive, and exclude the old duplicates?

* rsync?
* an automator script?
* other?

Is the directory structure the same? eg. are the three drives a backup of the same general drive with the same general folder structure?

You can use rsync for this, its a good tool. A little more information would of of help

1) you say backups, can you elaborate, what software, what structure etc
2) are you 100% sure that the files arent linked in any way, i.e multipart backups... i.e if file names match, you want the newest etc, but is there any consistency issues to think about.

If you answer the above we can help, rsync will work a treat

I wrote this article about using rsync over the network http://www.experts-exchange.com/Apple/Networking/A_3551-Backups-in-a-OSX-Mac-and-Windows-Network.html?sfQueryTermInfo=1+30+backup+osx

down the page is some rsync commands.

/usr/local/bin/rsync -aNHAXx --protect-args --fileflags --force-change --rsync-path="/usr/local/bin/rsync" sourcepath destinationpath

I removed the --delete option, the ideal solution would be to rsync 2 of the disks onto the third, potentially altering the partition sizes as you go.
