I used Apple's Backup in the past but found it excruciatingly slow and it didn't back up any applications nor any installer apps. Within the last few months I settled on SuperDuper! and have been very happy since. My backup strategy is this: I bought an external firewire drive that I located in the basement below where the computer sits. Ran a firewire cable through the wall. Partitioned the drive into 2 partitions: one partition big enough to back up my main drive on the computer and the second partition to handle odds and ends type of backups. I run SuperDuper! automatically every day to completely backup my main drive AND to make it bootable. It creates a clone on the external so that if anything goes south on my main drive, I simply boot off of my external. A daily backup takes about 12 minutes covering about 124G. I also have scripts that I run manually whenever I update specific files such as Quicken or other financial data. These backups take about 3-4 minutes and backup the specific files to a sparse disk image on my second partition. I used Automator/Applescript to develop these scripts which run as Finder plug-ins. With a little help from the Shirt-Pocket folks everything is running perfectly and for the first time in many years I have total peace of mind. In my case, if my system does develop problems, then my daily backup will simply copy that problem to my backup drive. SuperDuper! though has other modes (Sandbox?) that I think can prevent this type of problem. I just haven't had time to explore that feature.
