Data Domain: Dedupe Simplified

• High-speed, inline deduplication storage; disk target for nearline applications Any leading backup software, archive apps, or custom nearline use All data types: structured and file Any fabric: NFS / CIFS / NDMP via Ethernet, or VTL via Fibre Channel Disk storage: Internal, or gateway to SAN array One dedupe infrastructure: remote office, datacenter with inline replication

Challenge: Achieving the Data Protection Benefits of Virtualization

• Virtualization enables simplified data protection anddisaster recovery through the encapsulation ofsystems as files.

• However, there is often a significant storagerequirement in order to capitalize on these dataprotection benefits (i.e. image-level .vmdk backups)

Interestingly: 37% of organizations said the amount of data they need

to protect increased after implementing server virtualization*

Solution: Using Deduplication to Protect vmdk Files

Data Domain Deduplication Benefits Dramatic reduction in protected vmdk file

provides network-efficient disaster recovery over existing networks

Variable-Length Segments Are Critical• Data Domain variable-length segment deduplication can identify

change within each vmdk file

• Fixed segment lengths cannot deduplicate beyond the first point of data change:

Call me Izzy. Some years ago - never mind how long precisely - having little …

Call me Ish. Some years ago - never mind how long precisely - having little …

• Variable-length segments maximize redundancy!

Maximize Disaster Recovery Benefits

Eliminate Tape Dependency for Disaster Recovery

99% reduction in bandwidth required to replicate vmdk files

Rapid rebuild of virtual machines • Recover the entire virtual machine – system state,

configuration, file system and application data• Enable system rebuild quickly and easily into

dissimilar server equipment• Mix of physical and virtual systems all recoverable

from Data Domain deduplication storage

‘Green’ IT Initiatives Demand Efficient Storage

By 2012, de-duplication will be applied to 75% of backups.*-- Gartner

IT managers looking to boost storage efficiency next year willembrace online storage services, push de-duplication in the datacenter and adopt solid-state disk drives to help fuel hardwareconsolidation strategies and green initiatives.**

-- IDC

One-third of organizations with over 25TB of data cite that physicalfootprint and energy efficiency has become a more a importantpurchasing consideration of secondary storage systems***
