## Motivation When it comes to backing up a large amout of data, it is often preferable to only copy the modified and unique files, rather than simply coping the whole directory. The AmendmentBackUp (ABU) class provides a simple interface to do that. No dependencies are required apart from the Python 3 standard library.

## Design Say we have two folders, a source folder dir1 which you have your most recent files and a reference folder dir2 which holds some of your previous backup. What the ABU does is to compare all files in dir1 with those in dir2, and copy the files to a third destination folder dst. If you simply want to add the files to the original back, you can set dst to dir2.

## A quick example

## Limitation The ABU is best suited for when the source folder dir1 is a natural growth of the reference folder dir2. What I mean by natural growth is that there should not be too much renaming or move of the subfolders from dir2 to dir1. If that’s the case, using a version control system is probably a better option.
