Deduplication Storage Evaluation Criteria © Copyright 2011 EMC Corporation. All rights reserved. 18

Methodology: Inline vs. Post-Process Deduplication INLINE POST-PROCESS Deduplication Before Storing Deduplication After Storing Deduplication Store Deduplication 3 x disk accesses to shared store Other activities unimpeded − Predictable − Simpler 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 © Copyright 2011 EMC Corporation.
