Deduplication Storage Evaluation Criteria


Methodology: Inline vs. Post-Process Deduplication

POST-PROCESSDeduplication 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

DeduplicationStore

3x disk accesses to shared store
