EMC Avamar is a deduplication backup software that can: 1) Retain backups for longer periods while using less storage through 10-30x data reduction. 2) Replicate data more efficiently by only moving deduplicated data for bandwidth savings. 3) Provide reliable recovery through end-to-end data verification and continuous fault detection.

Retain more.
Retain backups longer, using less disk
10-30x data reduction eliminates the use of tape
for operational recovery
Replicate smarter.
Efficiently move data offsite – faster
Only move deduplicated data for 99%
bandwidth efficiency and cost-effective DR

At the source—Deduplication before data is transported across the network
At the target—Assures coordinated deduplication across sites, servers, and over time
Granular—Small, variable-length sub-file segments guarantee most effective deduplication
