This is a very basic Python script that allows backing up a directory and its contents, either by duplicating the whole tree, or creating a tar archive.
While usually the contents of the script would've been split into different files for a clear separation of concerns, we wanted to keep it simple and nothing is simpler that one single file.
Python is required for running this script. It was developed using Python 2.7.10, and as the time of writing this hadn't been tested on Python 3, but should work.
Configure your options in the config.yml file and then simple execute the script:
$ python backup.py
The configuration is done through a simple yaml file, where each block (starting with ---) represents a different backup configuration. Meaning you can use the same execution to backup multiple targets, with different rules for each.
You can use the supplied config.yml as reference and consult the docs here.
