Backing Up and Archiving Photo CD Images
Kodak’s Photo CD specification indicates that Photo CDs should have a useful life of over 200 years if stored under the recommended dark storage conditions (25°C, 40% RH). However, this has been called into question by more recent studies that have cast doubt on the BLER methodology used to arrive at this estimate. In addition, reports have surfaced of disk failures.

Famous quotes containing the words backing up, backing, photo and/or images:
“When I moved in with a bathing suit and tea bags
the ocean rumbled like a train backing up
and at each window secrets came in
like gas.”
—Anne Sexton (1928–1974)
“Better risk loss of truth than chance of error—that is your faith-vetoer’s exact position. He is actively playing his stake as much as the believer is; he is backing the field against the religious hypothesis, just as the believer is backing the religious hypothesis against the field.”
—William James (1842–1910)
“A photo of someone else’s childhood,
a garden in another country—world
he had no part in and has no power to imagine:
yet the old man who has failed his memory
keens over the picture— ‘Them happy days—
gone—gone for ever!’”
—Denise Levertov (b. 1923)
“no images of pastoral will,
But fear, thirst, hunger, and huddled chill.”
—James Vincent Cunningham (1911–1985)
