DR-Scout Architecture
The DR-Scout architecture is based on a set of fundamental design principles that provide for efficient, highly-scalable processing in the most demanding environments. Key design principles include:
- Support for near-zero RPO and RTO requirements
- Support for heterogeneous storage infrastructure (DAS, SAN and NAS) and host operating systems
- Integrated and comprehensive support for Near-Line and Disaster Recovery protection policies
- Elimination of backup windows
- Extremely low impact to production environments compared to other vendors' approaches
- Optimization of secondary storage use, to provide fastest recovery without any additional compression or loss of performance
- Leveraging of existing network infrastructure
- Usage of low-cost TCP/IP-based transport for remote replication
- Scalability to handle the needs of today's distributed environment
- Centralized management of local and remote data protection policies
The suite comprises two types of components: host-agents and control servers.
Host Agents include DR-Scout VX for volume-level continuous data protection, and DR-Scout FX for scheduled file-level protection. Each has a small footprint on the host, and only moves byte-level differences based on data changes.
DR-Scout CX is the Control and Media Server that provides for centralized management and offload of CPU-intensive operations necessary for efficient data protection. It includes a CDP/DR modeler to help IT accurately provision secondary disk storage and bandwidth.
The diagram below shows a typical deployment of DR-Scout in an enterprise datacenter, providing quick operational restore via CDP for outages of even one day or more, and efficient bandwidth utilization for longer-term Disaster Recovery and Remote Replication to a secondary site.

"InMage's bladed approach to software has changed our thinking about data continuity. Previously, the only disaster recovery choices were limited to either array-based software requiring duplicate - and costly -- devices on either end of the WAN, or host-based software that consumed precious application cycles. With DR-Scout, we are starting to define specific and accurate data continuity service levels that can be met and measured at lower cost with increased flexibility and tolerance to changing business requirements."
