By moving to disk-based deduplication across their remote offices, the company saw replicated data reduce to 10GB to 15GB and the backup window shrunk as they were able to reduce the amount redundant of data being moved by over 90 percent.
The question is no longer whether or not to dedupe, but how deduplication should be deployed and what is best for the IT environment?
In reality, deduplication is not about a single technology, it’s about selecting the right approach. This is why a number of storage vendors are working together in order to give organizations much greater flexibility in their dedupe options. By providing an interface between archiving and backup software and advanced disk-based storage appliances, organizations can now leverage an integrated platform that not only supports both source and target-based dedupe, but is also easy to manage.
Integrated deduplication within backup and archiving applications can provide unified data protection, from the remote office/branch office to the data center, and including both disk and tape, physical and virtual environments. From remote offices to the data center, these next-generation software solutions offer comprehensive protection and a single console for the management of all backup and recovery operations. Centralized management provides integrated data archiving, migration, and retention capabilities that address regulations for governance and compliance. Additionally, advanced reporting on backup and recovery operations enables service-level management of all protected data in the enterprise.
Organizations often choose this approach because deduplication is integrated into their existing backup and recovery application, giving them the ability to build a more customized solution. This also enables them to take advantage of valuable advanced data protection features such as support for storage lifecycle policies, media server load balancing, shared disk pools, and more.
Organizations may also opt for integrated source/client deduplication since this approach supports in-line deduplication of backup streams, which may be more likely to pinpoint duplicate content. The easy deployment of software-based deduplication also makes for a more simple deployment in remote locations. Furthermore, deduplicating as close to the source as possible will reduce the storage footprint. Because data will be deduplicated before transmitting over WAN connections, it will free- up critical network resources.
Considerations for Choosing the Right Approach
Deduplicating data everywhere can significantly help organizations benefit from robust management and tight integration with the backup/recovery platform without being locked into a specific hardware vendor or software solution. Organizations should consider a number of things in order to make the right decision around deduplication.
1. Think long-term about your dedupe strategy.
