If you buy a DVD you have a copy. If you want a backup copy you buy another one.
Only wimps use tape backup: real men just upload their important stuff on ftp , and let the rest of the world mirror it:;;)linus torvalds

Variable but forecastable renewables (wind and solar cells) are very reliable when integrated with each other, existing supplies and demand. For example, three German states were more than 30 percent wind-powered in 2007—and more than 100 percent in some months. Mostly renewable power generally needs less backup than utilities already bought to combat big coal and nuclear plants' intermittence.amory lovins
