T what backup software to use on a Mac

Just found out that Smartware will not atou bkup external drives on a Mac, only the internal HD.

What is a great and reliable bkup software to use with WD essential drives and an IMac?

Just bought a 2gb My Book Essential & need to have auto bkup for my large and growing photo collection.


If you have Leopard or higher, you can always us Time Machine, good application and free!!!
