The main problem with using S3 with BackupPC is that there's no rsync support, so you basically have to resend the whole file every time. That means slow backups and more expensive bandwidth charges. However, I finally was able to sign into Amazon EC2 (1) and I've been playing with it last week-end. Since there's no bandwidth charges between EC2 and S3, setting up a small server on EC2 with rsync or rdiff-backup could mean "offsite backup heaven" for backuppc users. Here's how I imagine such a system: You have a local BackupPC server (bpc) and a EC2 server image (ec2). ec2 uses S3InfiDisk (2) to store the data directly into S3. 1) bpc fires up ec2 using ec2-run-instances. 2) bpc knows when ec2 has finished booting using ec2-describe-instances, so when ec2 is booted, bpc starts rsync or rdiff-backup. 3) When the rsync is done, bpc shuts downs ec2 using ec2-terminate-instances.
