In search of a back up solution - Mozy.com

I am in search of a good automated backup solution for my personal computer(s).  Previously, I've just uploaded important files I want to keep onto my slice or some web hosting site.  I also use a 250GB Western Digital External HD to backup pictures and mp3s. But now, I want an online solution.  I want a service where I can "set it and forget it" to back up any or all the files on my multiple computers.  My first stop was at Mozy.com. I downloaded their Mac installer, which had the BETA description next to the download link. The install and setting up it to start backing up some files was easy.  The free 2 gigs for MozyHome is great.  But when I really got into customizing what I wanted to back up, I was disappointed.  I could not easily place rules to ignore certain files and folders.  It was all or nothing.  Also, Mozy takes the term "backup" very literally.  If you delete the file off your local machine, Mozy will delete the file from their backup servers in 30 days.  It is not intended to be used as a file repository. You can't easily share your backup files either.
For $4.99/month, I can get unlimited backup space.  But without being to easily exclude certain files and folders like .DS_Store and .svn folders, Mozy is a no go for me.If anyone can recommend something better, that would be super.
