In backup strategies, what does D2D2T stand for?

• A. Disk-to-Disk-to-Tape
• B. Data-to-Data-to-Transmission
• C. Direct-to-Device-to-Target
• D. Drive-to-Drive-to-Trust

Answer: (A)

The concept being tested is how backup workflows use multiple storage stages to balance speed and durability. Disk-to-Disk-to-Tape means you back up data first to fast, reusable disk storage, then create a second copy on another disk for redundancy and quicker restores, and finally move older data to tape for long-term archival and off-site protection. This layering lets you perform fast daily backups and quick restores from the disk tier, while keeping long-term, cost-effective retention on tape. Other options don’t align with standard backup terminology: data-to-data-to-transmission isn’t a recognized pattern; direct-to-device-to-target isn’t used in this context; and drive-to-drive-to-trust doesn’t describe a meaningful backup workflow.
