CloudBoost to Amazon Web Services

I am trying to wrap my head around using CloudBoost with NetWorker to get my backups safely offsite.  I have configured everything and even successfully ran the clone operation.  My question is, when does the data move from CloudBoost appliance to AWS?  How can I confirm the data is on AWS?  I was able to run a recovery operation and see that the Save Set was using the Default Clone Pool.  I am not convinced that this is pulling anything from the cloud, but more likely the CloudBoost VM.

Second question.  Should I be using Clone or Archive for this?  My brain tells me a clone will be an exact replica of when is on my DD2500.  If this is the case, wouldn't the retention policy of the DD2500 be pushed to the cloud storage too?  I only want limited time storage on my DD2500, but long term retention in the cloud.

Thanks,

Jeff
