I'm in the same situation. I use CrashPlan but I've heard CrashPlan has failed in the past so I just wanted another layer of security. I was thinking of finding some app like Tarsnap (and it should work with Glacier) that handles de-duplication really well.
I had read that Cyberduck can be used to backup to S3 and in-turn we can make a "rule" in S3 that after "N hrs" data in S3 should be sent to Glacier. But I don't how much price difference does it cause or whether we can directly back up to Glacier at all.
Duplicity is another thing I might want to explore. But absence of even a minimal GUI makes me a little uncomfortable.
