Computerworld - There are some issues that might seem worrisome to an IT administrator who's new to Linux, but they're really no problem once you look more closely. Among the areas you don't have to sweat, say customers, analysts and vendors, are backup and restore tasks, clustering and fail-over.
When it comes to data protection, most major vendors have ported their premier backup-and-restore tools to Linux. Examples include IBM's Tivoli Storage Manager, CA's ARCserve for Linux running on Intel systems, and CA's Brightstor for Linux on the mainframe.
To build clusters of Linux servers for instant fail-over in the event of a server crash, customers can use configuration scripts offered at Web sites such as that of the High-Availability Linux Project (www.linux-ha.org).
They can also use tools from distributors, such as the Cluster Manager Package for Red Hat's Advanced Server, or third-party tools such as LifeKeeper from SteelEye Technologies Inc. in Mountain View, Calif., and Matrix HA from PolyServe Inc. in San Francisco.
Some customers are finding that they can get faster fail-over and less of a performance hit when clustering Linux servers than when clustering Windows servers, says Vincent Re, chief architect at CA.

IDC White Paper: Linux in a Global Recession

Economic downturns have a tendency to accelerate emerging technologies, boost the adoption of effective solutions, and punish solutions that are not cost competitive or that are out of synch with industry trends. This IDC White Paper presents the results of an IDC survey of 330 companies in Western Europe, Asia/Pacific and the Americas that measures the receptiveness to Linux and takes into consideration changing views driven by the disruptive economic environment that businesses face today.
