Fetch'n'Backup - Simple two-step backup tool with rsync

fnb — Fetch'n'Backup

fnb is a simple two-step backup tool, powered by rsync. It gives you two handy commands: fetch (to pull from remote), and backup (to save to somewhere safe).

Under the hood? Just good old rsync — no magic, just sharp automation.

• Simple config. Sharp execution. Safe data.
• Use them one by one, or sync them all in one go.

🚀 Features

1. Fetch — Retrieve data from a remote server to your local machine
2. Backup — Save local data to external storage
3. Sync — Run Fetch and Backup together in one go
4. Init — Generate an initial config file (fnb.toml)

---

⚙️ Installation

From PyPI (Recommended)

pip install fnb
# または
uv pip install fnb

From Source

git clone https://gitlab.com/qumasan/fnb.git
cd fnb
uv pip install -e .

Requirements: Python 3.12 or higher is required.

🧰 使用例

# Initialize configuration files (fnb.toml and .env files)
fnb init

# Check the current config
fnb status

# Fetch: remote -> local
fnb fetch TARGET_LABEL

# Backup: local -> external  
fnb backup TARGET_LABEL

# Run Fetch → Backup in one go
fnb sync TARGET_LABEL

# Check version
fnb version

🔧 設定ファイル

config.toml

各処理対象のディレクトリごとに fetch / backup の設定を持ちます。

[fetch.SECTION_NAME]
label = "TARGET_LABEL"
summary = "Fetch data from remote server"
host = "user@remote-host"
source = "~/path/to/source/"
target = "./local/backup/path/"
options = ["-auvz", "--delete", '--rsync-path="~/.local/bin/rsync"']
enabled = true

[backup.SECTION_NAME]
label = "TARGET_LABEL"
summary = "Backup data to cloud storage"
host = "none"    # <- ローカル操作
source = "./local/backup/path/"  # <- fetchのtargetパス
target = "./cloud/backup/path/"
options = ["-auvz", "--delete"]
enabled = true

設定ファイルの優先順位（高 → 低）

1. ./fnb.toml ← プロジェクトローカル設定
2. ~/.config/fnb/config.toml ← グローバルユーザー設定（XDG準拠）
3. C:\Users\ユーザー名\AppData\Local\fnb\config.toml ← グローバルユーザー設定（Windowsの場合）
4. ./config/*.toml ← 設定の分割・統合用（開発/運用向け）

🔐 Authentication

SSH password input can be automated using pexpect. You can also define connection settings in a .env file if needed. Run fnb init env to create the initial .env file.

Version Management

This project uses automated semantic versioning with GitLab releases:

# Preview version bump
task version

# Execute version bump and changelog update
task version:bump

# Create GitLab release
task release

# Complete release workflow (test → format → bump → release)
task release:full

Current Version: v0.11.0 - View Release

CI/CD Pipeline

GitLab CI/CD pipeline provides automated testing, building, and deployment:

Stages:

• renovate: Automated dependency management (optional)
• test: Unit tests, code quality, Renovate-specific tests
• docs-quality: Documentation build validation
• build: Package building with uv build
• deploy-test: TestPyPI deployment (automatic on tag push) 🚀
• deploy-prod: PyPI deployment (manual approval for safety)

Automated Workflows:

# Deployment (v0.10.0)
tag push → [Auto TestPyPI] → Local Verification → [Manual PyPI]

# Dependency Management (v0.11.0)  
Monday 6am JST → [Renovate Scan] → [Auto MR] → [Enhanced Testing]

Optional CI Variables:

# GitLab Settings → CI/CD → Variables
TESTPYPI_API_TOKEN  # TestPyPI API token for testing releases
PYPI_API_TOKEN      # PyPI API token for production releases
RENOVATE_TOKEN      # GitLab token for automated dependency updates (new in v0.11.0)

Local CI Simulation:

# Run tests as they run in CI (unit tests only)
task test:ci

# Run unit tests only (fast feedback)
task test:unit

# Run integration tests only
task test:integration

# Run all tests
task test

# Verify TestPyPI deployment (v0.10.0)
VERSION=0.11.0 task verify:testpypi

# Dependency management tasks (new in v0.11.0)
task deps:update    # Update all dependencies
task deps:test      # Test with updated dependencies
task deps:security  # Check for security vulnerabilities

Test Structure

Tests are organized into two directories for optimal development workflow:

• tests/unit/: 9 files, 124 tests - Fast unit tests (1.65s)
• tests/integration/: 1 file, 23 tests - Comprehensive workflow tests (3.25s)

Both directory-based and marker-based execution are supported:

# Directory-based (recommended)
task test:unit          # tests/unit/ only
task test:integration   # tests/integration/ only

# Marker-based (backward compatibility)
pytest -m "not integration"  # unit tests
pytest -m "integration"      # integration tests

Test Coverage

Current test coverage is 87% (exceeds target, improved from 83% in v0.10.0) with comprehensive error handling and integration testing:

• backuper.py: 83% - Backup operation failure scenarios
• fetcher.py: 85% - SSH authentication and fetch failures
• cli.py: 99% - CLI command error scenarios
• reader.py: 89% - Configuration reading and validation
• gear.py: 87% - SSH automation with pexpect
• env.py: 68% - Environment variable handling

Integration Testing

Complete integration test suite with 23 tests (100% success rate):

• CLI Workflow Integration: 7 tests covering init → status → fetch/backup/sync workflows
• Multi-Module Integration: 6 tests verifying config → reader → gear → operation flows
• Sync Workflow Integration: 6 tests for complete fetch-then-backup sequences
• End-to-End Integration: 2 tests simulating realistic user workflows
• Test Infrastructure: Strategic mocking, external dependency isolation, reliable deterministic testing
