Deduplication Dramatically Reduces

Storage Capacity Requirements

Deduplication

10–30 times less data stored versus fulls + incrementals with typical retention policies

(9)

With Data Domain Deduplication Storage

Systems, You Can…

Retain longer

Keep backups onsite longer with less disk

for fast, reliable restores, and eliminate the

use of tape for operational recovery

Replicate smarter

Move only deduplicated data over existing

networks with up to 99% bandwidth

efficiency for cost-effective disaster recovery

Recover reliably

Continuous fault detection and self-healing

ensure data recoverability to meet service

level agreements

REPLICATE AFTER

DE-DUPLICATION

Backup de-duplication

Is Data Deduplication a Good Thing?

• Without De-Duplication



No reduction in local backup

storage



No reduction in replication time

and bandwidth



No reduction in offsite storage

• Leveraging De-Duplication



Reduced local backup storage



Reduced replication time and

bandwidth



Reduced offsite storage

(21)

Methodology:

Inline vs. Post-Process Deduplication

Post- Process:

Deduplication After Storing



The more processes, the more resource

contention

−

Copy to tape: Too slow to stream tape

−

Recovery: Service level agreement predictability

−

Replication: Poor time-to-disaster recovery

−

Deduplication : If interleaved with backup or

restore



More administration

to fight these issues

Deduplication

Store

3x disk accesses

to shared store



Other activities unimpeded

−

Predictable

−
