Arjun at The Productive Student questions whether online backup strategies make sense. He raises some good points. I’m still a fan of online backups as one part of my backup strategy. Specifically I use Jungle Disk to backup my frequently changing and important files to Amazon S2 infrastructure. As Arjun points out, this doesn’t give me the ability to get a bootable drive, but it does protect me in case I’m traveling and it gives me the ability to restore files to a previous version. I use Jungle Disk to backup DevonTHINK, iPhoto and specific document folders.
When I’m not traveling I use Time Machine and occasionally image a hard drive for safe keeping and to have an easily bootable option that I can bring up on another laptop if something catastrophic happens to my system.
