Can anyone verify that retrospect is good for backing up data? I would like to back up (clone) my system drive to a lacie firewire drive. I don't know much about this process so may not perfectly understand what needs to be done. I back up data on dvd's and external harddrives, but never used a program for it. I didn't want to purchase the program before asking around. In addition, does cloning or backing up your hard drive mean you don't have to reinstall third party programs, contacts, bookmarks, itunes, etc if you do a clean install or ever have to do a clean install? Also, is it more like putting a band aid on the situation opposed to actually reinstalling everything (is it better to reinstall or is the back up fine)? I appreciate any help. Thanks in advance.
