EMC Avamar

Highly efficient, variable-length deduplication through fast, complete daily backups.

EMC Avamar enables fast, efficient backup and recovery by reducing the size of backup data at the client—before it is transferred across the network and stored. Avamar’s variable-length deduplication dramatically reduces network traffic by sending only unique blocks over LAN/WAN. Blocks that were previously stored are never backed up again.

This provides huge savings in bandwidth for backup, a lot less disk storage needed on the back end, and most importantly very fast backups—often as much as ten times faster.

Avamar backups can be quickly recovered in just one step—eliminating the hassle of restoring full and subsequent incremental backups to reach the desired recovery point. The backup data is encrypted during transit across the network and at rest for added security.


Every Avamar backup is a full backup, which makes it easy for you to browse, point, and click for a single-step recovery.


Avamar Data Store features redundant power and networking, RAID, and patented RAIN technology to provide uninterrupted data accessibility. Daily data systems checks ensure recoverability whenever needed.


Data deduplication significantly reduces backup time by only storing unique daily changes, while always maintaining daily full backups for immediate single-step restore.


Deduplicated backup sends only changed blocks, reducing network traffic. Leverage existing LAN and WAN bandwidth for enterprise-wide and remote/branch office backup and recovery.


Avamar systems scale to 124 TB of deduplicated capacity, and can be deployed in an integrated solution with EMC Data Domain systems for high-speed backup and recovery of specific data types.
