Data-reduction product options
Data-reduction products have been available from different vendors for some time. EMC Corp. put object-based CAS on the map with its Centera product, but the firm draws a sharp distinction by positioning this product for fixed-content data archiving, not backup.
In the backup realm, there are several software and hardware products using data-reduction technology. Here's a brief rundown:
- Iron Mountain Inc.'s Connected DataProtector family of products uses block-level data-reduction technologies to protect laptops and desktops, as well as Windows file servers.
- Storactive Inc.'s LiveBackup products marry two technologies--continuous data protection and data reduction-- to protect laptops and desktops. The company's LiveServ for Exchange product also applies these technologies to protect Microsoft Exchange using less space than an Exchange information store.
- Avamar Technologies Inc. is a pioneer in applying commonality factoring and CAS to backup. Its Axion family minimizes network bandwidth and storage capacity through a full range of client and server applications and appliances designed to supplant the traditional backup environment.
- Data Domain Inc.'s DD400 and DD200 appliances provide an NFS- or CIFS-accessible "capacity-optimized storage" array that can provide disk storage for traditional backup or other applications.
As disk-based backup solutions mature, expect to see data-reduction technology incorporated into more products. The mainstream backup vendors haven't jumped on board yet, but it's only a matter of time. Less data means better backup performance and fewer dollars needed for backup storage, an impossible combination to resist.
