Not long ago network administrators would backup their data to tape storage, and later onto hard disks. As managed service providers evolved with technology, IT professionals began replicating to the cloud. Online storage services such as Amazon S3, Google Cloud Storage, DreamHost DreamCloud, and Dropbox became popular destinations for offsite data retention. It seemed like such a good idea at the time, since local disks were small and cloud servers were large. Storage technology has continued to improve, and 8TB hard disk drives are now available for local retention. As free space has increased on servers, so have the storage needs of its users. Internet bandwidth has not kept up with improvements in storage technology, and slow speeds or high prices have made it necessary to “reverse cloud” backup data from online containers to local disks.
