Initial backup can take a while to complete,
$ zpaq add "arc???" ./files/ -index local-index.zpaq 0.000000 + (955.283380 -> 687.840444 -> 622.268166) = 622.268166 MB 45.737 seconds (all OK)
but subsequent ones are almost instantaneous if no files were changed
$ zpaq add "arc???" ./files/ -index local-index.zpaq 0.000000 + (0.000000 -> 0.000000 -> 0.000104) = 0.000104 MB 0.408 seconds (all OK)
