A lightweight Docker container for backing up Docker volumes to local storage or various cloud services with rotation and encryption.
docker-volume-backup is a lightweight Docker container designed to automate the backup of Docker volumes. It handles recurring or one-off backups to various storage destinations, including local directories, S3, WebDAV, Azure Blob Storage, Dropbox, Google Drive, and SSH-compatible storage. The tool also includes features like backup rotation, GPG encryption, and notifications for backup status.
DevOps engineers, system administrators, and developers who manage Docker-based applications and need reliable, automated backup solutions for their containerized data volumes.
Developers choose docker-volume-backup for its simplicity, lightweight design, and flexibility in supporting multiple storage backends. It integrates directly into Docker setups without requiring complex configurations, offering essential backup features like encryption and rotation out of the box.
Backup Docker volumes locally or to any S3, WebDAV, Azure Blob Storage, Dropbox, Google Drive or SSH compatible storage

The Docker image is under 25MB, minimizing resource overhead and ensuring quick deployment, as emphasized in the README.
Supports backups to local storage, S3, WebDAV, Azure, Dropbox, Google Drive, and SSH, allowing hybrid or multi-cloud strategies as listed in the features.
Integrates with the Docker socket to stop containers during backup via labels, ensuring data consistency without manual intervention, as shown in the compose example.
Includes GPG encryption for sensitive data and notifications for backup status, providing essential security and monitoring out of the box.
Requires mounting the Docker socket, which can expose the host to security vulnerabilities if not properly secured, a trade-off acknowledged in the setup instructions.
The README does not mention support for incremental backups, leading to potentially larger backup sizes and longer transfer times for frequently updated volumes.
Relies on numerous environment variables for setup, which can be error-prone and cumbersome compared to GUI-based or declarative backup tools.
