PowerProtect Data Manager Appliance 5.15.0.0 Administrator's Guide for DM5500

Backup Data encryption

Customer backup data is encrypted at rest. Data encryption protects Customer's backup data if the protection system is stolen or if the physical storage media is lost during transit, and it eliminates accidental exposure of a failed drive if it is replaced.

When backup data enters the protection system using any of the supported protocols, the stream is segmented, fingerprinted, and de-duplicated (global compression). It is grouped into multi-segment compression regions, locally compressed, and encrypted before being stored on the appliance file system.

Once enabled, the encryption feature encrypts all backup data entering the system. You cannot enable encryption at a more granular level.

Key Management Interoperability Protocol

Key Management Interoperability Protocol (KMIP) is a client/server communication protocol for the storage and maintenance (management) of keys, certificates, and other objects. KMIP facilitates data encryption by simplifying encryption key management keys that are created on the key manager.

PowerProtect Data Manager Appliance supports the following KMIP-compliant key managers:

  • KeySecure
  • NextGen
  • Data Security Manager (DSM)
  • CipherTrust
  • Security Guardium Key Lifecycle Manager (GKLM)

To use a KMIP key manager, configure both the key manager and the protection storage system to trust each other. A protection storage system will retrieve these keys and their states from the key manager after establishing a secure TLS connection. When applicable, keys are pre-created on the key manager. External key management supports both Active Tier and Cloud Tier storage.
