Which type of deduplication method is performed by HP StoreOnce D2D devices?

A.
object-level differencing

B.
pre-hash data encrypting

C.
metadata compressing

D.
hash-based chunking

Explanation:

HP D2D (Disk to Disk) Backup Systems use Dynamic deduplication(hash-based chunking) technology
that provides a significant price advantage over our competitors.
Note:
* HP offers two complementary deduplication technologies that meet very different customer
needs:
/ Accelerated deduplication (object-level differencing) for the high-end enterprise customer who
requires:
– Fastest possible backup performance
– Fastest restores
– Most scalable solution possible in terms of performance and capacity
– Multi-node low-bandwidth replication
– High deduplication ratios
– Wide range of replication models
/ Dynamic deduplication (hash-based chunking) for the mid size enterprise and remote office
customers who require:
– Lower cost device through smaller RAM footprint and optimized disk usage
– A fully integrated deduplication appliance with lights-out operation
– Backup application and data type independence for maximum flexibility
– Wide range of replication models
