I'm trying to improve my overall back up system, and could really use some advice... -I've happily used TimeMachine, but I've been told that I should supplement it by backing up with Carbon Copy Cloner and/or SuperDuper. Are there any benefits to using these app's that TimeMachine doesn't provide? If so, what are they? -If it's NOT advisable use Carbon Copy Cloner and/or SuperDuper, should I use another app for further back ups? -I do a lot of sensitive work that requires serious privacy and protection. I'd like to back up using some kind of online service, but only if it could be seriously protected / encrypted. I know iDisk is available, but have also been told that I can use DropBox with some encryption / protection services that would make backing up files on a remote server ultra protected. So, what's the most recommendable route? -I store a lot of media on external hard drives, and would like to make back ups of those drives. What's the best software to use for scheduled, incremental back ups for external HD to external HD file back ups? Thanks, guys!
