CDP Buyer's Guide - Second
(from the SNIA CDP Buyer's Guide,
"The SNIA DMF CDP SIG defines
CDP as follows: Continuous data protection (CDP) is a methodology that
continuously captures or tracks data modifications and stores changes
independent of the primary data, enabling recovery points from any point in
the past. CDP systems may be block-, file- or application-based and can
provide fine granularities of restorable objects to infinitely variable
recovery points. So, according to this definition, all CDP solutions
incorporate these three fundamental attributes: 1. Data changes are
continuously captured or tracked, 2. All data changes are stored in a
separate location from the primary storage, and 3. Recovery point objectives
are arbitrary and need not be defined in advance of the actual recovery.
There are a number of recognized technological approaches to delivering CDP,
including block-, file- and application-based. Today, many vendors offer
varying degrees of support and awareness of specific application and data
environments. But regardless of the underlying technological approach
utilized, CDP can offer faster data retrieval, enhanced data protection and
increased business continuity with lower overall cost and complexity."
