Continuous Data Protection with Unlimited Snapshots A data snapshot is simply a point-in-time image of your stored files. Snapshot technologies are useful for creating copies of large data volumes without the need to actually move all the data or consume large amounts of space. When data is generated by multi-tasking, multi-users, or within virtualized environments, it is changing at a rapid pace. In these cases, traditional backup techniques always lag behind the actual data changes.
Pointer-based snapshots are an effective data protection solution for the following reasons: • High level of data protection, recoverability and availability while maximizing system up-time • Automated data protection with no performance impact or capacity waste while applications are running • Zero data loss, the ability to meet recovery point objectives (RPOs) and continuous data protection without negatively impacting performance • Fast recoverability As with any great idea, true snapshots also h
Pointer-based snapshots and writable clones are just two of the many new enterprise-grade data protection capabilities available in every ReadyNAS OS 6 appliance from NETGEAR. These technologies were once the exclusive domain of high-priced, complex enterprise storage. With NETGEAR ReadyNAS OS 6, businesses of any size now have access to these powerful tools.
