I don't have Leopard as of yet (waiting on Adobe updates before updating the OS), but I am wondering if there will be any reason to continue to use the Backup program if I decide to use Time Machine. I have a dedicated hard drive on my main computer (Mac Pro) and use Backup every day to keep current. When I install Leopard, and if I use Time Machine, is there any reason to have BOTH Backup and Time Machine? I just found it odd that I got a .mac e mail discussing updates (see next paragraph), including an update to Backup 3 for Leopard...why do that (eaning why did Apple impove Backup) if Time Machine is 'better'. Backup 3 update. The latest version of Backup, version 3.1.2, improves general stability and provides compatibility with Leopard. If you haven't already updated your copy of Backup, choose Software Update from the Apple menu or download the latest version from Member Central. Thoughts?
