Just picked up a program called Arq (http://www.haystacksoftware.com/arq/) for OS X that backups a machine to Amazon S3. You pay Amazon based on standard storage and bandwidth costs (http://aws.amazon.com/s3/pricing/) and it allows for reduced redundancy storage, so you're looking at about 10cents a gig per month.

Based on your note above, for 385 gigs you're looking at about $36/month ($432/year) -- and that's before you get smoked on transferring all that data to Amazon, which will cost you about 10 cents a gig and run you about $39 for a one time transfer.

Once most those files hit S3 you won't have to re-send them (just backup newly changed files) but Mozy's $439.89 is still looking like the cheaper option.

I've been using Arq for a little while now (former Mozy user) and can recommend it. Arq is substantially better than some of the other S3 backed storage solutions as it takes steps to minimize S3 traffic, keeps incremental backups of recently changed files (ala Apple Timemachine), and an open sourced (Github) restore client in case they go out of business and you need to restore your files.

If you're worried about cost, you can also use their Reduced Redundancy storage which would save you a chunk out of that.
