Deduplication reduces the amount of disk storage needed to retain and protect data by an average of 10-30 times, making disk a cost-effective alternative to tape for protecting backup and/or archive data. Data on disk is available online and onsite for longer retention periods, and restores and retrievals become fast and reliable. Storing only unique data on disk also means that it can be cost-effectively replicated over existing networks to remote sites for safe, reliable tape-free disaster recovery. EMC Data Domain deduplication storage systems continue to revolutionize backup, archiving, and disaster recovery with high-speed, inline deduplication. Data Domain systems scale from smaller remote office appliances to highly scalable systems for protecting backup and/or archive data at large enterprise data centers.
