WHITE PAPER
Data Invulnerability Architecture:
Ensuring Data Integrity and Storage
System Recoverability
Data Domain protection storage systems represent a dramatic departure from
conventional storage system design thinking and introduce a radical premise:
No single mechanism is sufficient to ensure data integrity in a storage system.
Data Domain systems have been designed from the ground up to be the storage of last resort. Because the Data Domain operating system (DD OS) is purpose-built for data protection, it comprises an architectural design whose goal is data invulnerability.
There are four critical areas of focus:
- End-to-end verification
- Fault avoidance and containment
- Continuous fault detection and healing
- File system recoverability
