-Author: Ludy87
-Description: This script processes JSON translation files for localization checks. It compares translation files in a branch with
-a reference file to ensure consistency. The script performs two main checks:
-1. Verifies that the number of translation keys in the translation files matches the reference file.
-2. Ensures that all keys in the translation files are present in the reference file and vice versa.
-
-The script also provides functionality to update the translation files to match the reference file by adding missing keys and
-adjusting the format.
-
-Usage:
-    python check_language_json.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]
-"""
-# Sample for Windows:
-# python .github/scripts/check_language_json.py --reference-file frontend/public/locales/en-GB/translation.json --branch "" --files frontend/public/locales/de-DE/translation.json frontend/public/locales/fr-FR/translation.json

 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 on a configurable schedule (default: daily at midnight via `system.databaseBackup.cron`). This ensures that there is always a recent backup available, minimizing the risk of data loss.
+   - 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
