Steam Cloud Save Downloader GUI is a user-friendly graphical application that lets you download and back up your Steam Cloud save files automatically. This tool ensures that your game progress stored on Steam Cloud can be safely saved locally and restored whenever needed — especially useful if a cloud save becomes corrupted or overwritten.

This project is ideal for PC gamers who want peace of mind knowing their game saves are backed up and easily accessible.

🚀 Features

📁 Automatic backup of Steam Cloud saves

Retrieve and store your cloud saves on your local machine in organized folders.

🪟 Graphical user interface (GUI)

Makes it easy to browse, authenticate, and download save files without using command-line tools.

🔄 Version rotation

Keeps multiple backups of your save files with versioning to roll back to older states.

🧠 Session authentication

Save sessions are stored securely so you only need to authenticate once per session period.

☁️ Game coverage

Works with Steam games that support Steam Cloud. If a game does not support cloud saves, it cannot be backed up.

🛠 Getting Started

Authentication

Before downloading your save files, you need to authenticate with Steam:

1. Open the application. 2. Enter your Steam username when prompted. 3. A session file will be created locally after authentication (no password is stored). 4. This session typically stays active for about one month, depending on your network and IP changes.

📥 Downloading Save Files

Once authenticated:

1. Select the Steam Cloud saves you want to download from your games list. 2. Choose where to store the backup files locally. 3. Run the download process. 4. Your save files will be organized under directories labeled with the Steam App ID for each game.

🔄 Backup Rotation & Versioning

When backup rotation is enabled:

Older versions of save files will be saved with a suffix like .scsd_1, .scsd_2, etc.

This allows you to restore earlier versions of your save if needed.

🗓 Scheduled Backups

To automate save backups:

Windows: Use Task Scheduler to run the application at regular intervals.

macOS/Linux: Use cron jobs to schedule automatic execution.

🛡 Rate Limiting

Even though this tool does not use the official Steam API, it adheres to Steam’s unofficial request limits (up to around 85,000 calls per day) to avoid triggering rate limits or being flagged as abusive. The application waits briefly between requests to lower the risk of issues.

📁 Docker Support

A Docker image is available for running scheduled backups automatically. Example:

BASH

mkdir data

docker run -d \ --name scsd \ -v .//data \ -v /etc/localtime:/etc/localtime:ro \ hhhhojeihsu/scsd:latest docker exec -it scsd scsd_auth <username>

Volume mounts:

| Mount | Purpose | | --------- | --------------------------------- | | /data | Save files and app data storage | | /config | Configuration files (scsd.conf) |
