FlashCopy is an IBM feature supported on various IBM storage devices that makes it possible to create, nearly instantaneously, Point in Time copies of entire logical volumes or data sets. The Hitachi Data Systems implementation providing similar function is branded as ShadowImage. Using either implementation, the copies are immediately available for both read and write access.
Famous quotes containing the words flash and/or copy:
“Here lies a man who was killed by lightning;
He died when his prospects seemed to be brightening.
He might have cut a flash in this world of trouble,
But the flash cut him, and he lies in the stubble.”
—Anonymous. From Booth, Epigrams Ancient and Modern (1863)
“This made you first to know the Why
You liked, then after to apply
That liking; and approach so one the tother,
Till either grew a portion of the other;
Each styled by his end,
The copy of his friend.”
—Ben Jonson (1572–1637)
