A backup chain is restored/exported by extracting each of the tar files in order. This can cause files updated in multiple of the delta backups to be extracted and overwritten multiple times.

A more efficient method would be to use the contributions of each delta to only extract the files that actually contribute to the final state. This could prevent a lot of unnecessary file writes.
