OK the Riverbed Whitewater appliance can move data to AWS Glacier while keeping some percentage of it cached on the appliance. This doesn't really make a lot of sense. AWS Glacier is for long term archiving. It doesn't matter that much how quickly the Whitewater appliance can move the data to AWS Glacier. What will matter is when you need to get the data back it will take a long time to do it with AWS Glacier. Most data retrieval jobs from AWS Glacier will take 3-to-5 hours to complete. I'm a big fan of local caching of backup data and putting a deduped compressed and encrypted copy in an S3-compatible storage service but when the data you need is not in the appliance cache it will have to retrieve it. Retrieving it from an S3-compatible storage service is going to be a lot faster than the hours it will take for AWS Glacier to find it and get it ready. If the data being backed up to the Whitewater appliance is strictly for archival purposes then there would be no need to cache it on the appliance and moving it to AWS Glacier would then make a lot more sense....
