docker-volume-backup
Backup and rotate Docker volumes to local storage or remote backends
docker-volume-backup is a lightweight companion container for backing up Docker volumes. It supports both recurring and one-off backups, can store archives locally and/or on remote storage backends, and can rotate old backups automatically.
Key Features
- Scheduled or on-demand backups of one or more Docker volumes
- Multiple targets: local archive plus optional remote backends (S3-compatible, WebDAV, SSH, and others)
- Configurable rotation/pruning of old backups for supported backends
- Optional container stop/restart during backup for improved consistency
- Optional GPG encryption for backup archives
- Notifications for successful or failed backup runs
- Works with Docker Compose and supports Docker Swarm mode
Use Cases
- Automated backups for stateful Docker services (databases, app data, configuration)
- Shipping volume backups to an S3-compatible object store for offsite retention
- Simple backup companion service for homelabs and small production stacks
Limitations and Considerations
- Developed and tested primarily against Docker CE; other engines may work but are not guaranteed
It is designed to be small, easy to integrate into existing Docker stacks, and flexible in where backups are stored. For teams and individuals running stateful containers, it provides a pragmatic approach to volume backups without needing a full backup platform.
