EMC Data Domain Encryption

EMC Data Domain Encryption provides encryption of data-at-rest that safeguards user data in the event of theft or loss of physical storage media using industry-standard RSA® BSAFE FIPS 140-2 validated cryptographic libraries. With DD Encryption, backup and archive data is stored on a Data Domain system with encryption and compression performed inline—before the data is written to disk. It is supported on the following EMC Data Domain deduplication storage systems:

Key Features

  • Secure Data Management: Encrypts all user data using administrator selectable, industry-standard 128-bit or 256-bit AES algorithms
  • Inline Encryption: Integrates with inline deduplication to encrypt data as it is written to disk to ensure your entire system is protected
  • Key Management and Integrity: Leverage built-in internal key management or external key management via RSA Data Protection Manager
