19 19© Copyright 2011 EMC Corporation. All rights reserved. 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 DeduplicationStore 3x disk accesses to shared store  Other activities unimpeded − Predictable − Simpler INLINE Deduplication Before Storing Deduplication
