As photographers – many of us digital – we live with the threat that our entire life's work can be wiped out in a second. It's all there, sitting in a magnetic registration on a hard drive... Even redundant systems can fail. Here's my obssessively redundant system: Click the diagram for a hi-res close up. - My Aperture library sits in full on my MacBook Pro's 320GB HDD. - The entire contents of the MBP are automatically backed up to a 1TB Time Capsule - A second Time Machine drive is stored offsite in a bank safety deposit box - An Aperture Vault is stored in the same deposit box - In addition, I send all my 4 and 5 star rated photos in full res to an online SmugMug account - Separately, I archive my company's completed project dockets to an HDD connected to the Time Capsule. - The project dockets HDD is backed up periodically to an FTP online space. I stopped using optical media as backup because you only discover that your backup didn't burn properly when you lose your original files and go to the DVD for desperate hope that you didn't lose it all. My iPhoto library (personal photos) is on a Mac Mini, backed up to the 1TB Time Capsule and these photos along with my iTunes library has "backups" held in my tv and iPod. Please share your setup and any backup nightmare and "THANK GOD I BACKED UP" stories.
