Avamar:

1. Divides data into sub-file segments

2. Determines if segments are unique or duplicate

3. Backs up only data that is unique

4. Sends data compressed and encrypted

Deduplication is the Enabler

Avamar Data Store


Every backup is a “full” backup; restore single files or full directories directly to the client

Methodology: Inline vs. Post-Process Deduplication

POST-PROCESSDeduplication 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

DD Boost Software• Distributes parts of deduplication process to backup

server or application clients– Licensable software works across Data Domain portfolio

• Supports majority of backup software market– EMC Avamar and NetWorker– Symantec NetBackup and Backup Exec

• Speeds backups by up to 50 percent

• Process more backups with existing resources– 20–40% less overall impact to backup server– 80–99% less LAN bandwidth

• Enables Data Domain replication management from the backup application

DDBoost


Data Domain Replicator• Network-efficient and encrypted

• Transfers only compressed, deduplicated data over the WAN

• Consolidate up to 270 remote sites into a single system

Additional Data Domain Software Options

Data Domain Virtual Tape Library• Easily integrates with Fibre Channel

• Emulates multiple tape libraries

• Supports open systems and IBM i operating environments

Data Domain Encryption• Inline encryption of data at rest

• Satisfies internal governance rules and compliance regulations

• Protects against theft or loss of a physical system

Data Domain Retention Lock• File locking to satisfy IT governance

and compliance policies

• Electronic data shredding
