Docker Volume Backup
Backup and restore Docker named volumes with one command. Supports scheduled backups, S3 upload, retention policies, and container stop/start around backup windows.
Why?
docker-compose down -v deletes all your data. A corrupted volume is gone forever. Docker has zero built-in volume backup. This image fixes that.
Quick Start
One-time backup
bashdocker run --rm \ -v /var/run/docker.sock:/var/run/docker.sock \ -v ./backups:/backup \ -e VOLUMES=myapp_data,myapp_db \ zachbg/docker-volume-backup:latest
Scheduled backup (every 6 hours)
yamlservices: vol-backup: image: zachbg/docker-volume-backup:latest restart: unless-stopped volumes: - /var/run/docker.sock:/var/run/docker.sock - ./backups:/backup environment: VOLUMES: myapp_data,myapp_db SCHEDULE: 21600 RETENTION_DAYS: 7
Restore
bashdocker run --rm \ -v /var/run/docker.sock:/var/run/docker.sock \ -v ./backups:/backup \ -e RESTORE_FILE=myapp_db_20250115_120000.tar.gz \ -e RESTORE_VOLUME=myapp_db \ zachbg/docker-volume-backup:latest restore
