EMC NetWorker Design Best Practices with Data Domain

By Ken Ciolek and Natalie Meek, GlassHouse Technologies, Inc.

Data Domain deduplication storage integrates with standard NetWorker architectural and operational environments and provides a highly cost-efficient nearline storage solution for enterprises of all sizes. This paper provides an in-depth analysis of how Domain deduplication storage offers new storage architecture options for EMC NetWorker customers.

NetWorker environments support a handful to thousands of clients. NetWorker scales by adding additional NetWorker storage node/SAN storage nodes, and associated disk and tape resources. The most common challenges in NetWorker environments include:

Completing backups, staging and cloning with limited time and physical resources
Contending with large client backups (several million files per client)
Scaling NetWorker databases, logs, media management and pools to keep up with demand
Eliminating redundant data backup locations (multiple full/incremental copies of databases, aggressive backup retention policies, etc.)
Eliminating performance bottlenecks (NetWorker server type, networking, client issues, etc.)
Lack of capacity planning and reporting disciplines

The authors walk through a detailed analysis of how Data Domain systems address these challenges, complete with planning and sizing considerations and integration planning.

"We see a particularly compelling case for Data Domain to revolutionize the way small, medium, large and remote NetWorker sites manage physical storage resources and replication for disaster recovery. For extremely large NetWorker instances, appropriate planning, sizing, and integration strategies make the Data Domain system a viable solution for the enterprise."
