Nice article explaining the way Time Machine in Mac OS X 10.5 (Leopard) backs up your data. Time Machine and full backups.
I bought a 500 Gig internal SATA drive last week at the corner computer shop for backup purposes. It cost me 109 euros. I can remember buying a 250 Gig drive for close to 400 a few years ago. Drives are cheap and big nowadays!
Pop quiz: given that the backup application is called Time Machine and Mac OS X allows you to name a harddrive, what is the name of my new backup disk?
John Siracusa of Ars Technica has some more technical bits about hard links for the nerds among you. OS X 10.5 Leopard: the Ars Technica review.
Update, the question has been answered in the comments.
