Access "The modernization of backup: More disk, less tape"
This article is part of the Vol. 9 Num. 2 April 2010 issue of Primary storage dishes up dedupe
ESG's 2010 Data Protection Survey shows that the trend away from tape continues, with the economics of both deduplication, for disk-based backup, and cloud storage, for long-term retention, contributing to tape's decline. Ranked as the No. 3 IT priority by more than 500 respondents to ESG's 2010 IT Spending Intentions Survey, "improving data backup and recovery" takes priority over a number of other IT initiatives and was edged out only by "increasing the use of server virtualization" and "information security initiatives." And among backup and recovery projects, disk-assisted data protection is expected to dominate this year and beyond. The introduction of disk to improve the speed and reliability of backup and recovery is a top consideration for companies of all sizes -- especially as data deduplication changes the economics of the investment. And while tape-based strategies are often required and even desired for long-term retention, the economics of introducing a cloud storage tier for this purpose looks promising. And in its recent 2010 Data Protection ... Access >>>

Dedupe and compression cut storage down to size
by W. Curtis Preston
Data reduction technologies like data deduplication and compression have been well integrated into backup systems with impressive results. Now those benefits are available for primary storage data systems.
SRM tools struggle to meet today's demands
At one time, storage resource management (SRM) applications tried to be all things for all storage shops, with little success. Modern data storage environments require new tools to navigate the intricacies of virtualized environments, but the jury's still out on whether storage management vendors can meet those needs.

SAN consolidation with director-class switches
by Dennis Martin
A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features.
Tape may be teetering, but it's still a big part of backup ops
Tape no longer holds the place it once did in most firms' backup environments, but most storage shops still rely on it to some degree. Our Snapshot survey finds that while the vast majority of respondents use disk in backup, nearly 40% plan to buy tape gear this year.

Seeking clarity in the clouds
After you wade through the confusion that vendors have created, you'll find there are advantages to both public and private cloud offerings.
The solid state of storage efficiency
Storage managers want to use their storage systems more efficiently and vendors are finally forking over the tools to do it; but there may be a catch as vendors are faced with decreasing disk sales.
