ESG Lab Report: Data Domain Replication

For users of disk-based backup appliances, the ability to replicate, or mirror, data between two backup to disk systems (one onsite, one offsite) provides an added layer of data protection in the event of a disaster. This type of process is commonly referred to as one-to-one replication. However, in more advanced scenarios, replication support can be expanded to include many-to-one and bi-directional configurations, which provide greater flexibility.

This ESG Lab Report validates that Data Domain data replication options are easy to integrate into existing LAN/WAN infrastructures and provide the following benefits:

  • Data Domain systems provide organizations with optimal flexibility by enabling any combination of replication configurations, one-to-one, many-to-one and bi-directional, simultaneously.
  • Data Domain deduplication technology optimizes capacity at remote sites and reduces bandwith requirements over the entire network.
  • Data Domain replication provides a multi-site data recovery solution that is low cost and easy to use. Backup administrators use familiar tools and procedures.
  • Data Domain systems identify redundant files and data before they are written to disk, creating a storage footprint that is 10x-30x smaller on average than the original dataset

“By combining de-duplication and data compression into one package, Data Domain can significantly reduce backup expenditures by reducing the amount of storage capacity and bandwidth that is ultimately required during the backup and DR process. Inline de-duplication, compression, cross-site deduplication and bandwidth reduction are compelling, valuable and fundamental capabilities of the Data Domain offering.”
