I have been thinking about my own backups for some time. Do you guys prefer rolling your own setup for full system backup or use services like CrashPlan? Do you guys trust services like S3/Glacier? When backing up your system do you bar specific files from being backed up like GPG/SSH keys, etc.?
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.
