Since I already use Retrospect to backup my files on my Mac there is no reason to install it on my XP box. I just installed the Client on XP and now my TiBook backs up both my Mac files and my PC files to my 10 GB Firewire drive. That's another thing that irks me, no friggin bus powered Firewire in the PC world. it makes life so easy to just plug in the drive where ever I need to. I want to use my 60 GB Firewire drive on my PC (its got my MP3 collection among other things) so I have to get a power supply for the drive. grrr... It didn't come with one because it is a bus powered drive. well thanks to Dad (thanks Dad) he is sending me one of his extra ones saving me $15! While typing this I backup up My Documents, Application Settings and Local Settings. well My Documents is still going, but its going pretty quickly. all I am using is a 10 baseT hub, no router or anything. pretty slick. One less thing to worry about now, all my important WORK files are backed up daily. next on the list of things to get working on my PC is to actually install my printer :-D yes I know I am lazy. its not a high priority as I can print from my Mac just fine :-P Well after doing a spell check the backup is complete in 77 minutes. I am impressed I have never backup up a PC to a Mac before, but it sure beats installing the full Retrospect on the PC. plus this way I can backup both my computers at once to one drive.
