We wish to create a backup tool that will save only the last modified files of a storage unit.

In our example, the storage unit is not a bucket.

The storage unit is the DD-MM-YYYY-test branch of the current descartes-underwriting/devops-technical-test-data git repository.

The descartes-underwriting/devops-technical-test-data repository is not frozen and will have new commits.

Commits will be added to the DD-MM-YYYY-test branch multiple times every day.

The DD-MM-YYYY-test branch name will be adapted using standard datetime convention eg: 01-01-2022-test for the 1st of January 2022.

Develop a backup tool to save the modified files at each commit.

Script and data should be saved on a private candidate/descartes-backup-project repository on your github account.

Access should be granted to all members of the descartes-underwriting group:

https://github.com/orgs/descartes-underwriting/people

Create a script to automate the backup process using open source software.

The script should track the changes fo the branch DD-MM-YYYY-test of the descartes-underwriting/devops-technical-test-data repository.

The execution of the script should be carried out with a github-action / gitlab-pipeline or any other tool automating git workflow on your git project.

It is highly recommended to use a scheduling tool to execute the back up process.

The backup should store files in separate folders.

The backup file structure should be based on the sha1 of the descartes-underwriting/devops-technical-test-data.

For the following commits on the descartes-underwriting/devops-technical-test-data:

The candidate/descartes-backup-project repository should have
