Ok, I was using SuperDuper ever since I started using OS X, and it worked fine. Then today I was going to do a backup and it just sat there, doing nothing, FOREVER. It would finish the first part, the prepping or whatnot, but when it came time to actually copy files, it would just stop and not do anything. Tried reinstalling it, same thing. so I installed CCC, and it seems fine. Anyone have a preference and if so, why? I want to know what the best backup solution out there is.
