Data Deduplication

The DXi-Series disk backup and replication systems use Quantum's patented data deduplication technology
to dramatically increase the role that disk can play in data protection. With DXi-Series solutions, users can
retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays. This advantage
allows IT departments to cost-effectively retain months of backup data on disk for faster, more reliable
restores and more data recovery points. Quantum's innovative implementation of this core technology
means that users do not have to compromise on performance to take advantage of extended retention
capability. Inline data flow provides streamlined deduplication that offers a maximum combination of total
system performance, manageability, and value.
