ORLANDO, Fla. - Storage Networking World (SNW) -- EMC today moved to strengthen its disk-backup technology by acquiring data de-duplication specialist Avamar for $165 million.
Avamar was among the pioneers of the de-duplication technology that is becoming popular in virtual tape library (VTL) products and is catching on among customers looking to reduce or eliminate the amount of data backed up on tape. (See De-Dupers Demand Disk Mindset and DMV Green Lights Remote Backup.)
De-duplication software only transmits data that has changed since the last backup, greatly reducing the amount of data that needs to be stored and moving it faster over the network. (See Insider: De-Dupe Demystified.) Backup vendors Asigra and Avamar and VTL startup Data Domain were early players in de-duplication, although the ranks of vendors with that technology have swelled in recent months.
EMC chief development officer Mark Lewis sees Avamar's Axion software as a major addition to its Legato backup software platform.
When Symantec acquired backup market leader Veritas last year, EMC hoped to capitalize on the transition by moving into the No. 1 spot. Not only did it fail to catch Symantec, but EMC has lost ground to IBM in overall storage software as well. EMC's backup and recovery software -- which includes Legato and other products -- grew a mere three percent year over year last quarter.
