"Almost unlimited coping of recoverable data using PCR"

Actually, this would not be as trivial as it sounds. Especially the unlimited coping.

It's actually not hard to do. In theory, a single PCR reaction with only two primers could copy the entire data set in a few hours.

Are you sure you understand the concept AND the limitations of PCR? I predict: No.

There are many forms of DNA. Single stranded, double stranded, circular etc. etc. I assume we were talking about non-circular DNA. ds/ss does not matter, for PCR you would have to go ds anyway. You realize that strand shortening would be a problem? I could think about ways to correct this but it is not trivial.
