## 🎯 Goal
|
||||
|
||||
This project automates the backup of Docker volumes using incremental backups (rsync) and supports recovering both files and database dumps (MariaDB/PostgreSQL). A robust directory stamping mechanism ensures data integrity, and the tool also handles restarting Docker Compose services when necessary.
|
||||
|
||||
## 🚀 Features
|
||||
|
||||
- **Incremental Backups:** Uses rsync with `--link-dest` for efficient, versioned backups.
|
||||
- **Database Backup Support:** Backs up MariaDB and PostgreSQL databases from running containers.
|
||||
- **Volume Recovery:** Provides scripts to recover volumes and databases from backups.
|
||||
- **Docker Compose Integration:** Option to automatically restart Docker Compose services after backup.
|
||||
- **Flexible Configuration:** Easily integrated with your Docker environment with minimal setup.
|
||||
- **Comprehensive Logging:** Detailed command output and error handling for safe operations.
|
||||
|
||||
## 🛠 Requirements
|
||||
|
||||
- **Linux Operating System** (with Docker installed) 🐧
|
||||
- **Python 3.x** 🐍
|
||||
- **Docker & Docker Compose** 🔧
|
||||
- **rsync** installed on your system
|
||||
|
||||
