I was pretty excited when Amazon first announced its new Glacier product. This offering allows archiving of data at $0.01 per GB per month with a 3-5 hour recovery time. Now they have added a feature to automatically archive S3 storage to Glacier based on rules set by admins. I haven’t used it yet, but it seems that CloudBerry will be first tool for SMBs to check out when exploring online backups. For $79.99, their Server offering seems to be a great deal. We will be testing this in our new lab at Hurricane Electric soon.
UPDATE 8/30/15: We are using this for some clients and it works well..
