Avamar Backup and Deduplication
Unlike anything else in the industry

Network

Reduce:
• Data moved by 95% Avamar Data Store

• Network interface card usage at the client by 95%
• Backup windows by 90%
• Client CPU usage by 80%
• Disk access at the client by 50%
• Memory usage at the client by 50%


Deduplication is the Enabler

Avamar Data Store

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


Recover in One Step
Avamar daily full backups eliminate need to restore last full/incremental

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

Deduplication Store Deduplication

3x disk accesses

 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
