Greetings, So I've run into a Mac issue I'm not sure how to handle. I've got a mac pro running Leopard. I've got 3 internal Harddrives: 1.) 250 GB (runs my OS and applications), 2.) 500 GB (where I store all my source files for my business), 3.) 750 GB (serves as the backup for Time Machine for all the files on Harddrives 1 and 2.). So I began thinking the other day. What would happen if somehow all 3 harddrives were destroyed (theft, fire, power surge, flood damage, etc.)? I would lose years worth of source files from my business (graphic and web design files mostly). So I went and bought a 1 TB external drive today. Ideally I would like to put the external drive in another location and bring it out maybe once a week to backup the 3rd harddrive from above (the one being used for Time Machine). Does anyone have any suggestions on how to backup this harddrive...some type of program that essentially acts like Time Machine? I just basically need it to mirror my Time Machine Harddrive. I found a program named Super Duper (http://www.macupdate.com/info.php/id/13803/superduper) ... not sure if anyone has had experience with it or not. I'm open to any suggestions on how to use the external harddrive to back up my Time Machine harddrive. Thanks!
