Methodology:Inline vs. Post-Process Deduplication INLINE POST-PROCESS Deduplication Before Storing Deduplication After Storing Deduplication Store Deduplication 3x disk accesses to shared store  Other activities unimpeded  The more processes, the more resource − Predictable contention − Simpler − 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 2012 EMC Corporation.
