Looking for a good and cost effective solution (which are hopefully not mutually-exclusive) for long term archiving of full system backups. I've read many comments that EC2 snapshots cannot be copied to AWS Glacier (snapshots are stored in S3) but I suspect that this simply means there's no "trivial" way to do it. Digging deeper, via scripting or coding or such, is Glacier a feasible mechanism and has anyone worked on it yet?
