A NAS gateway offers file-based accesses to external storage on a disk array -- or a SAN, where users can take advantage of superior performance and reliability while maintaining a level of simplicity. Since storage is moved off of the NAS device, interoperability and connectivity are crucial issues, and virtualization is increasingly important for superior scaling and utilization of the storage resources. The product snapshots in this chapter highlight key specifications for a cross section of major NAS gateway products.
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.
Backup and replication software are powerful tools used to protect data against loss due to hardware failure, natural disasters, and other problems.
