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. The following products were selected based on input from industry analysts and SearchStorage editors, and vendor specifications are current as of October 2006.

The following specifications have been provided by vendors and are periodically updated. Vendors are welcome to submit their updates and new product specifications to sbigelow@techtarget.com.

    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)
