Bob: Your new article on Backups is pretty PC-Centric. I know it is your website and all, but could I write a small addendum for options for the Macintosh?
Sure if Macs are significantly different from PCs. I assume you can just add external USB or firewire drives like you can on a PC. Backup software is probably different though. The principle of having two external drives and backing up one to the other (or running them as a RAID sytem) presumably holds.
I could add a "box" with the comments for Mac users.
