Tape may be teetering, but it's still a big part of backup ops
This article is part of the Storage magazine issue of Vol. 9 Num. 2 April 2010
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. You have to search far and wide these days to find a company that's not using disk to some degree in their backup operation. In our latest Snapshot survey, only 6% of respondents said they don't use disk at all for backup. On the flip side, 18% have completely eliminated tape from their backups. Among those companies that do use disk, the methods break down relatively evenly, with many companies using more than one disk-based technology. The most popular way to use disk was simply as a file system that acts as the backup target (53%). Just using disk as a staging area or temporary cache before spinning off to tape was a close second at 49%, while 37% said they use virtual tape libraries (VTLs) for backup. But tape's days are far from numbered despite an apparent ...

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.
A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features.
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.

After you wade through the confusion that vendors have created, you'll find there are advantages to both public and private cloud offerings.
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.
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.
