My project to move my backups to Amazon S3 was derailed for a number of reasons, and lately I’ve been thinking in completely the opposite direction. I’m thinking instead of getting an Airport Extreme and attaching it to an external hard drive and backing up everything to that. The comments on the previous posts about the cost of S3 when you have a lot of data to back up kind of gave me pause, and then I found out about S3’s performance for myself. I’m passing for now, although there are still some “absolutely can’t lose” files that I’m storing there.
