CDP platform specifications

Continuous data protection (CDP) products track changes to files and data -- typically in real time -- recording activity and allowing recovery to an extremely granular level. This effectively reduces backup windows and restore points, allowing busy transactional data centers to protect mission-critical applications without significant downtime for backups or restorations. In most cases, CDP is implemented as software running on a server with internal or network storage access. The following product snapshots highlight key specifications for a cross-section of CDP systems/appliances currently available.

    NOTES:

    (1) SNIA defines "true" CDP as "a methodology that continuously captures or tracks data modifications and stores changes independent of the primary data, enabling recovery points from any non-predetermined 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". This is different from the definition of snapshots. (http://www.snia.org/education/tutorials/2006/spring/data-management/Disk-based_Restoration_Technologies.pdf page 37)
