I'm using time machine with an external drive on my macbook for all my documents. However in the off chance something happens to the apartment while I'm not there I'd like some kind of remote backup set up for the items on my mac (mainly documents and pictures). Looking for what other people do to address this issue. Automated backups to an iDisk? Once a month manual backups to an external you keep somewhere else? Some fancy custom setup with Amazon S3?
