An overview of restore and recovery technology, and Double-Take Availability
Linux, once an operating system for computer enthusiasts and contrarians, is now installed on primary production servers in business computing environments around the globe. The deployment of Linux saw a dramatic uptick in 2008, in part because of macroeconomic events that took place in primary trade centers around the world. Today, Linux, in its various forms, is going strong. Even first-tier computer hardware manufacturers like IBM have embraced specific distros of Linux for their System x hardware.
Regardless of whether you’re running critical business applications on Linux, Windows,
UNIX or another mainstream operating system, every organization faces critical intervals when system downtime is unwelcome—whether it’s planned or unplanned.
Increasingly, shops that were able to accommodate modest periods of downtime for backups and system maintenance are finding increased server demands are closing backup windows. Globalization and expanding online business opportunities have been a big contributor to the unwelcomed contraction of periodic backup opportunities.
Since nearly all organizations need to keep their systems available for increasing
amounts of time, they are now realizing that a system outage of even a few hours will result in disruption, chaos and wasted capital. For many companies, exposure to anything more than an hour or two of downtime has become unpalatable. Current backup processes that include tape or removable disk media fall short of serving the availability and recovery needs of businesses. Shops that thought they weren’t candidates for a high availability solution are now feeling an urgent need to start looking at high availability options.
