Access "Backup apps take small steps to improve encryption"
This article is part of the Vol. 6 No. 1 March 2007 issue of Using file virtualization to improve network-attached storage
Very few storage managers use the encryption option in their backup software apps, fearing the performance penalty--swelling data volumes and exhausted processing cycles--if they do. To alleviate this, some backup vendors are moving encryption from the client to the media server. But users are slow to get onboard. "We've been toying with the idea [of encryption] for 18 months, but I am still really worried about performance," says Marty Scott, manager of network solutions for the department of transportation in Maricopa County, AZ. Scott performs a full 6TB backup over the weekend and is pushing a 60-hour window to get it done. "I am hesitant to add any more in there as it will take longer," he says. But he's ready to take a look at new offerings. "We need to do something." Last December, Symantec announced its Media Server Encryption Option (MSEO) for Veritas NetBackup that offloads client-side encryption to the central backup server to speed up the process. "The media server is generally a bigger box ... so [encryption] has a negligible impact here," says ... Access >>>

Rein in NAS with file virtualization
NAS filers have sprung up largely unchecked in many companies, creating major management headaches and forcing companies to reevaluate how they handle this critical piece of storage infrastructure. File virtualization appliances can address multiple filer pain points by pooling disparate storage, providing a global namespace and making short shrift of data migrations.

Are you ready for new compliance rules?
Two things to know about storage and regulator compliance: There's no single technology product that meets all compliance requirements and there's plenty of prep work to do before you even think about technology. The first step is to define your unique requirements, including compliance and litigation-readiness needs, as well as business productivity and service-level objectives.

Power costs put the squeeze on storage
Storage shops keep growing and growing, adding capacity to keep up with the business. But the cost of powering all that additional capacity and keeping it cool is growing, too, and some data centers are being pushed to their limits. Thinking green can help stem the tide of soaring power costs and also help you figure in the cost of end-of-life disposal for your aging equipment.
Swap tape for removable disks
New removable disk drives combine the speed and reliability of disk with tape's portability. But widespread enterprise adoption may be inhibited until problems, such as costly disk drives and incompatibility with some major backup software products and automated tape libraries, are solved.

Are backups a waste of time?
by James Damoulakis
Data protection is now much more specialized due to increased user expectations and new technology options. We need to rethink the way we approach risk and risk-related services.
iSCSI: Learn it or be left behind
by Jon Oltsik
Thought you might get by without considering iSCSI storage? Think again. With continuous progress on the iSCSI protocol and steadily improving products, the technology is now gaining enterprise stature. Savvy users should prepare themselves now for iSCSI.
