Company Overview:
EMC’s $165m purchase of Avamar Technologies in 2006 provided the company with valuable de‐duplication technologies that were proven in the remote office/branch office (ROBO) data protection space. EMC then repackaged the technology into an easy‐to‐deploy hardware appliance (Avamar Data Store) that can back up data at remote offices and funnel it into centralized repositories at the data center.
• Launched Avamar 4.1 in December 2008
• Launched Avamar Data Store Gen 2 in May 2008
Key Products/ Services:
Software: Avamar 4.1
In late 2008, EMC introduced Avamar 4.1. This software‐only product deduplicates data globally and at the source for fast, secure backup and recovery across your enterprise—including VMware environments, remote offices, and data center LANs.
Software: Avamar Virtual Edition for VMware This product is an Avamar server deployed as a virtual
appliance—the industry’s first fully virtualized de‐duplication backup and recovery solution.
Hardware/Software: Avamar Data Store Avamar Data Store Gen 2 is a complete backup and recovery package — including de‐duplication software agents, backup software, (EMC‐certified) physical servers and disk storage, and high availability.
Avamar backup and recovery solutions utilize patented global data deduplication technology to identify redundant data at the source, minimizing backup data before it is sent over the LAN/WAN. With Avamar, you can achieve new levels of data reduction and enable fast, secure backup for your VMware environments, remote offices, and data center LANs. In the process, you’ll reduce backup time, growth of secondary storage, and network utilization.

Strengths
- Global deduplication at the source and the target minimizes storage footprint
- Granular — Small, variable‐length sub‐file segments guarantee effective de‐duplication
- Broad platform and application support
- High availability and reliability – Fault tolerance across nodes with RAIN architecture improves reliability
- Centralized management allowing users to control multisite backups from a single location and automate policy based management Weaknesses
- Avamar software agents can negatively impact application and server performance (Up to 15%)
Weaknesses
- Must use Avamar branded or EMC‐certified hardware
- The technology was not designed to meet the high performance requirements of enterprises
- Difficult to restore an entire RAIN architecture after a disaster. (lots of deduplicated data scattered)
- Dependent of the node: before backing up / restoring a check is made to verify the deduplicated blocks available. This can lengthen the time for backup and restores
- Permanent activity on Nodes: Data is permanently moved from node to other
