Q:

Are electronic copies of aircraft logbooks acceptable for reconstruction?

This question about a pilot losing the logbook for an aircraft got me thinking about acceptable means to reconstruct logbooks. Reconstructing the logbooks is not a trivial process (or a cheap one). Aircraft logbooks can be lost, misplaced, or destroyed for many different reasons.
There is a big focus on electronic flight bags (EFB's) with electronic logbooks, some sites dedicated to providing electronic logbook services for pilots, but nothing about the airframe/engine logs themselves. 
So the question is, would the FAA and potential buyers accept electronic copies of the airframe/engine logbooks as legal record equal in value to the paper copies? 
Edit
I'm curious if digitizing old records (scanning) is acceptable for electronic records. The AC for digital records has a lot of emphasis on digital signing by the original signatory, but isn't so clear on the use of a scanned copy of a signature being an acceptable backup for paper records.

A:

According to FAA's advisory AC 120-78A, it is perfectly acceptable to maintain electronic records for airframe/engine.
