Trying to keep two external drives updated

[BrianSchnurr]

Hey everyone,

I currently have a 128GB microSDXC card in my MacBook Pro, and I also have a LaCie drive connected as well. I have partitioned my LaCie drive into three partitions. One partition has the same exact files that is on the memory card. I want to keep it updated with eachother, without having to do it manually. There are a lot of files. What would be the best way of doing this?

Also, if there is a free solution, that would be amazing

For example, I keep all my design resources(I am a web designer), on my memory card for when I am out with clients, and I use my LaCie to back that up.

Thanks!

Several choices, both not free, however: Chronosync and Carbon Copy Cloner. Of the two, Chronosync would probably work best for what you need to do and it's currently discounted $10.
