What Does Disk-to-Disk-to-Cloud Mean?

Disk-to-disk-to-cloud (D2D2C) is an approach to hybrid cloud backup in which data is stored locally before it is backed up on cloud servers by physical means.


D2D2C involves physically transporting hard drives (or other storage media) to the cloud provider's facility. 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.

Techopedia Explains Disk-to-Disk-to-Cloud

Disk-to-disk-to-cloud operates by saving the data to be backed up on tape or hard disks and then delivering the storage media to the cloud backup vendor where it will be attached to 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.
