Access "The future of virtual machine backup"

Published: 30 Oct 2012

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.
