# Descartes Underwriting
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Property
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Task
|
||
|
|
|
||
|
|
Develop a backup tool to save the modified files at each commit.
|
||
|
|
|
||
|
|
### Submission
|
||
|
|
|
||
|
|
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>
|
||
|
|
|
||
|
|
Especially:

|
||
|
|
|
||
|
|
### Script
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
### Data
|
||
|
|
|
||
|
|
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`.
|
||
|
|
|
||
|
|
Starting from the initial commit [282180fe7e5d9cbf297f2f0ef813cffe60ce2328](https://github.com/descartes-underwriting/devops-technical-test-data/commit/282180fe7e5d9cbf297f2f0ef813cffe60ce2328), all the history should be backup.
|
||
|
|
|
||
|
|
## File structure example
|
||
|
|
|
||
|
|
For the following commits on the `descartes-underwriting/devops-technical-test-data`:
|
||
|
|
|
||
|
|
| SHA | OPERATION |
|
||
|
|
|-----|-----------|
|
||
|
|
| Commit_N | create readme.md |
|
||
|
|
| Commit_N+1 | create doc.txt |
|
||
|
|
| Commit_N+2 | create data/test/test.txt |
|
||
|
|
| Commit_N+3 | append text to ./doc.txt |
|
||
|
|
| Commit_N+4 | create test/project/project1.txt |
|
||
|
|
|
||
|
|
The `candidate/descartes-backup-project` repository should have
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ tree .
|
