It's time for me to look into serious back up solutions for a Mac Pro dual boot. I had good backup solutions in the past, but this set up is different. I now have two Mac drives (system and storage), the Windows partition on Mac system drive, and one Windows storage drive (total 3 physical, 4 virtual). Physical system drive is 240GB split down the middle. Mac storage drive is 1TB, and XP storage drive is 500MB. I keep reading about robotic backup systems like Drobo, but I'm wondering what the advantages are over simply getting matched drives and mirroring them. (Other than the fact that I don't have to worry about drive sizes I mean). It seems to me the big selling point on these gadgets is the "set it and forget it" aspect. Am I missing something? I've used mirrored drives in the past, and don't recall ever having to pay any attention to them, no extra software settings. Share them, don't share them, whatever. That, and they update on the fly. Every time I write to the primary drive, the redundant drive is instantly updated to match it. What am I not getting? These "robotic" backups just seem to me to be nothing more than SATA drive racks with a lot of blinking lights I don't really need (I pay attention to my storage capacity. I know when it's getting full long before the lights come on), and software that does stuff the system can already do. If I am missing something here, could someone please enlighten me?
