[TECH] Automatic Directory Compare Software? by "Josh Koffman" .

I think the best way to explain what I'm asking is to describe the situation. I have a drive that holds my main active music collection. It's about 80GB worth of music that means a fair bit to me. I keep it on an external drive and I have copies of the data on two other drives. I add to the main drive fairly frequently. What that currently means is that to ensure that my backups are current I go in to the backup drive, delete all 80GB of data, then copy it all again. It takes quite a while and isn't really efficient. What I'm looking for is like a drive cloning software but that will work on only a specific directory. It has to be manually triggered as my backup drives aren't usually connected to the live system. What I'd love is a small (preferably free) utility that will do a diff, find out the missing files, and sync the backup drive to the source drive. Any suggestions? I haven't found anything that takes care of this but perhaps I'm looking in the wrong places? Thanks!
