+# New Database Backup and Import Functionality
+
+**Full activation will take place on approximately January 5th, 2025!**
+
+Why is the waiting time six months?
+
+There are users who only install updates sporadically; if they skip the preparation, it can/will lead to data loss in the database.
+
+## Functionality Overview
+
+The newly introduced feature enhances the application with robust database backup and import capabilities. This feature is designed to ensure data integrity and provide a straightforward way to manage database backups. Here's how it works:
+
+1. Automatic Backup Creation
+   - The system automatically creates a database backup every day at midnight. This ensures that there is always a recent backup available, minimizing the risk of data loss.
+2. Manual Backup Export
+   - Admin actions that modify the user database trigger a manual export of the database. This keeps the backup up-to-date with the latest changes and provides an extra layer of data security.
+3. Importing Database Backups
+   - Admin users can import a database backup either via the web interface or API endpoints. This allows for easy restoration of the database to a previous state in case of data corruption or other issues.
+   - The import process ensures that the database structure and data are correctly restored, maintaining the integrity of the application.
+4. Managing Backup Files
+   - Admins can view a list of all existing backup files, along with their creation dates and sizes. This helps in managing storage and identifying the most recent or relevant backups.
+   - Backup files can be downloaded for offline storage or transferred to other environments, providing flexibility in database management.
+   - Unnecessary backup files can be deleted through the interface to free up storage space and maintain an organized backup directory.
+
+## User Interface
+
+### Web Interface
+
+1. Upload SQL files to import database backups.
+2. View details of existing backups, such as file names, creation dates, and sizes.
+3. Download backup files for offline storage.
+4. Delete outdated or unnecessary backup files.
+
+### API Endpoints
+
+1. Import database backups by uploading SQL files.
+2. Download backup files.
+3. Delete backup files.
+
+This new functionality streamlines database management, ensuring that backups are always available and easy to manage, thus improving the reliability and resilience of the application.
