Access "Tape security... with compromises"
This article is part of the Vol. 4 No. 11 January 2006 issue of Boosting data storage array performance
Security. Performance. Affordability. Pick two. Storage administrators who have been instructed to secure their organization's backup tapes are grappling with this reality. The bulletproof, high-performance encryption appliances offered by vendors like Decru (now owned by Network Appliance) and NeoScale Systems come at a cost of $25,000 or more per appliance (see "Encryption appliances reviewed," this issue). Encrypting data in software is cheap, but it places a huge load on the host, and can double the time it takes to complete a backup. Quantum's new DLTSage Tape Security represents the latest approach--it's fast and free, but may not pass muster with regulatory agencies or be an ample deterrent for a dedicated "black hat." DLTSage Tape Security is a firmware addition to Quantum's existing DLT-V4 drives, and will be included on the next generation DLT-S4, due out this quarter.

Cut big backups down to size
by James Damoulakis
Disk-based backup can help companies struggling with the inefficiencies of tape, but you may experience sticker shock at the cost of moving to disk. Data-reduction technologies can trim backup data down to size, and make the price of disk a little easier to swallow.
