Why backup?  Goals –Backups are done for restores  Operational  Disaster Recovery –Disaster recovery requires offsite backup –Operational recovery requires onsite backup –Need both onsite and offsite copies on disk –Need quick restores  Don’t have time for moving physical assets –Protection of personal data & intellectual property

Why So Much Interest in Data Deduplication?  Backup & Archive processes have been overwhelmed by information growth  Primary storage efficiency has become a necessity to cope with massive growth  ROI drives the compelling appeal of Dedupe –Reduced Storage Capacities –Lower Infrastructure Costs –Improved SLA’s –Efficient Replication for Business Continuance/DR Very important In useEvaluating / In Near – Long Term planNot in Plan Deduplication One of the top 10 Technology Considerations 59% 24% Deploying Deduplication 55% 21% - Source: TheInfoPro Wave 11 Storage Study, 2008
