The document discusses data deduplication technologies and the "Backup Redesign Initiative". It notes that 40% of large enterprises now use deduplication, resolving old debates around its safety and scalability. The Initiative aims to fully transform backup to be disk-centric rather than tape-centric, integrating deduplication, replication, and virtual machine image-based backup directly into backup software. This will provide faster and more automated disaster recovery.

5. Deduplication: How Far Have We Come?
• Today, We Can:
– Scale to Store Multiple PBs of Backup Data on a Single System
– Ingest, Deduplicate Inline AND Store Data as Fast (or faster)
than VTLs Can Simply Store Data
– Replicate/Consolidate Data from up to 270 Remote Sites
– Encrypt, Lock Data for Information Governance/Compliance
– Significantly Slash Backup Window Timing/ Recover Flawlessly
– Crush Backup Data by 20-30x (40-60x for virtualized data)
– Minimize or Completely Eliminate Tape Use

6. Old Issues We No Longer Need to Debate
• “Target” Versus “Source” Dedupe
• “In-Line” Versus “Post Process”
• “Is Dedupe Safe?”
• “Can Dedupe Systems Scale?”
• “Is Tape Dead?”

• “Copy to Tape” mandate sometimes “embedded” into companies’ compliance processes, so
legacy tape hard to completely eliminate, many co’s still archive to tape
• When tape market rate of decline is juxtaposed against typical data growth rates (35-
45%/year) …the trend becomes clearer

8. What is True Dedupe?
• Today, Over 25 Vendors Offer Data Reduction Technologies
Under the “Dedupe” Name
• Types of Dedupe
– SIS (Single Instance Store) 3-4x typical
• Useful for primary storage (increases capacity utilization) , but not for backup/DR
– Sub-file Level 20-30x typical, non virtualized
– “Bolt On” versus “Integrated” Solutions
• “True Dedupe” Characteristics:
– Enables Backup Data to Become Mobile Enough for Efficient Network-
based Replication Using Existing WAN Resources
• Requires 90% or more data reduction
– Uses Less Versus More Disk (Inline-no landing cache necessary)
• Fast Ingest & Restore Speeds, smaller footprint and power consumption
– Initiates Replication During the Backup Process
• Fast Time-to-DR
– Dedupe Designed into Architecture (whether SW or HW-based)
– Enables Full Automation of Processes

25. Dedupe is Enabling Next Gen Backup Now!
“By 2014, deduplication will be a standard feature in all backup
products and applied to 75% of backups.”
“EMC Acquires Data Domain, Becomes Deduplication Leader,
Signals Deduplication as a "Must Have" Capability”
Dave Russell, Research VP, Gartner
August 2009
“Deduplication has become a must-have feature for vendors in the backup/recovery market.
The value of data reduction technologies, such as deduplication, cannot be understated.”
“New Storage Solutions Can Modernize Data Life Cycle Management”
