Disk-to-Disk-to-Cloud (D2D2C)

Disk-to-disk-to-cloud operates by saving the data to be backed up on typical hard disks and exporting data to the cloud backup vendor by installing or attaching the physical disk within the vendor’s infrastructure. This technique provides the same backup solution as in a normal cloud backup but differs in the way data is backed up on the cloud infrastructure, eliminating the more typical Internet-based data backup procedure by sending physical disks to the backup provider.

Disk-to-disk-to-cloud is used primarily in conditions where the risk of uploading data via the Internet is high and/or the size of data is so large that Internet backup is difficult or impossible.
