Warranty is in no way predicated on issues of copyright or ability to backup. Warranty law applies to a copy of A Court of Thorns and Roses the same way it applies to a copy of Frankenstein.
Warranty is about fitness for use, merchantability, and honoring sales contracts. It has nothing to do with issues of intellectual property.
If you sold someone a book, filled with public domain content, and the ink faded after a week, you can't just throw up your hands and say that the buyer should have made another copy. You'd likely be liable for warranty of merchantability.
