Data protection

Vblock Data Protection overview

This section presents the following information:

•

Defines data protection

•

Describes the optional VCE Vblock Data Protection capabilities

•

Illustrates and describes the typical, standard data protection configurations for backup and recovery

•

Illustrates and describes the typical, standard data protection configurations for business continuity

and workload mobility

The information in this section assumes prior knowledge of EMC Avamar, EMC Data Domain, and EMC

VPLEX.

Data protection defined

Data protection encompasses a wide range of different technologies, techniques and methodologies used to

ensure the integrity, availability, and currency of both the data and the underlying delivery systems in an IT

environment. For Vblock systems, data protection is defined as:

•

Backup and recovery: Minimum required data insurance.

–

Provides protection against data corruption, accidental data deletion, storage component failure,

and site disaster.

–

Ensures backups are fully recoverable, point-in-time copies of data that are typically done once

per day.

•

Replication of data snapshots: Additional data insurance.

–

Provides additional level of data protection on top of daily backups since replication cannot always

protect against data corruption.

–

Takes multiple snapshots, or nearly continuous snapshots, throughout the day to reduce worst

case data loss from 24 hours to time of last snapshot.

•

Business continuity: Application availability insurance

–

Ensures zero data loss and near-zero recovery time for business-critical data.

–

Provides additional level of data protection on top of daily backups since replication cannot always

protect against data corruption.
