# Bind-mount a local directory This example shows how to back up a host directory by bind-mounting it into the Zerobyte container. It uses the simplified setup (no remote mounts). ## Prerequisites - Docker + Docker Compose ## Setup 1. Copy the env file: ```bash cp .env.example .env ``` 2. Edit `.env` and set `HOST_DATA_DIR` to the directory you want to back up. 3. Start the stack: ```bash docker compose up -d ``` ## Use in Zerobyte - Create a new volume of type **Directory** - Select the mounted path shown in the compose file: `/mydata` ## Access - UI/API: `http://:4096`
