Deduplication 2.0 addresses the problems that Deduplication 1.0 created. Like many innovative solutions, Deduplication 1.0 products addressed some critical challenges, but in the process, created new ones for customers. Deduplication 1.0 products focused on individual point solutions and as a result led to incompatible deduplication algorithms. They also were driven by backup performance, not recovery performance. Dedupe 2.0 solutions require:
- Federated deduplication
- Restore performance that is at least 80% of the ingest performance
- High availability
StoreOnce offers Federated Deduplication which provides deployment independence for deduplication. HP is able to provide deployment independence because its research arm, HP Labs, developed a deduplication engine that can be deployed across a storage infrastructure -- from virtual machines to enterprise data centers. The use of a common deduplication engine enables the native communication and movement of data across the various systems without rehydrating the data. This increases the efficiency of the deduplication process and permits data to be moved from location to location over low-bandwidth, affordable links. HP has used Federated Deduplication in its StoreOnce family since 2010. The recently released HP B6200 StoreOnce Backup System brings this approach to large data centers. HP has also moved Federated Deduplication into a software solution – namely its backup application, HP Data Protector. So, HP’s vision of using a single, consistent technology throughout the organization for deduplication is rapidly being realized.
