# Backup Interface

The **Backup Interface** in the CloudBox system allows users to manage, download, and replay backup files. Backup files contain important timing data, ensuring event integrity and enabling post-event analysis. Proper management of these files helps maintain smooth operations and fast retrieval when needed.

## Backups

This section shows all backup files stored locally on the CloudBox. Each file is timestamped (`YYYYMMDD-HHmmss.txt`) for easy identification.

**Functions**

* **List Files**: Displays the available backup files.
* **Download Backups**: Downloads all backup files as a single ZIP archive.
* **Delete All**: Permanently removes all stored backup files.

Keeping this section clean is important to prevent the system from becoming slow during rewind operations.

## Rewind Passings

The **Rewind** function allows replaying of past passings stored in backup files.

**Fields**

* **Start Timestamp**: Defines the beginning of the time range to rewind.
* **End Timestamp**: Defines the end of the time range to rewind.

**Buttons**

* **Rewind**: Starts the process of replaying passings from backup files.
* **Clear**: Resets the timestamp fields.

**Behavior**

* If no timestamps are set, all passings from the backup folder are replayed.
* Replayed passings are sent to connected TCP clients and, if the CloudBox is bound, also to the Cloud Passing Ingestion Service.
* Rewinding large amounts of data can take longer if many backup files are present.

## Important Considerations

* **Regular Cleanup**: Delete old backups after downloading them externally to keep the CloudBox efficient. Large volumes of files can slow down rewind operations.
* **Backup Download**: Always archive backups outside of the CloudBox. Files can be downloaded directly via the interface or by navigating to:

  ```
  http://{clbx_ip_address}:2999/download
  ```

  Example:

  ```
  http://192.168.1.11:2999/download
  ```

## Summary

The **Backup Interface** provides essential tools to handle race data securely and efficiently. By listing, downloading, deleting, and rewinding backup files, operators ensure that no critical information is lost and that event timing data can be retrieved whenever necessary.

Regularly cleaning up backups and archiving them externally guarantees both system performance and long-term data safety.
