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.
