The future of virtual machine backup

The data center will have a very different look five years from now. Here's a prediction: lots and lots of virtual machines running on VMware, the open-source Xen, Microsoft's Virtual Server or some other yet-unknown platform. In 2004, total market revenue for virtual machine software grew at 30%, says Dan Kusnetzky, VP of IDC's system software research, with VMware enjoying the lion's share of the market. In the coming years, he says, "open source and a highly competitive market will drive down the price" of virtual machine software—and thus of revenue growth—but "it will not in any way slow down the adoption." Storage managers responsible for data protection may be wondering whether virtual machine backup happens any differently than it does on single operating system/single server systems. In theory, there's nothing about a virtual machine that says you can't back it up the old-fashioned way: by installing a backup agent that traverses the file system. The problem some VMware shops have had with that traditional file-level ...

    There are four main ways to consolidate NAS--upgrading to larger traditional NAS boxes, clustered file systems, parallel file systems and NAS aggregators. We help you determine the best consolidation option for your storage environment.

  • The future of virtual machine backup

  • Get ready for virtualization

    The benefits of virtualization are apparent, but getting there is another matter. Many products can deliver some form of virtualization, but behind the promises of storage utopia looms vendor lock-in. But even if the rewards are greater than the risks, you still need to assess which virtualization options are mature enough to deploy.

    Storage Bin: The storage market is a soap opera filled with subplots and backstabbing. But trying to win business by lying about your competitor's product or service is a loser's maneuver.

  • Get ready for real ILM

    ILM product initiatives today generally amount to little more than repackaging old products with new names, says Stephen Foskett. But you can still get ready for real ILM with tiered storage, consolidation and a service-oriented approach.
