+# Script: host_backup.sh
+# Description: This script securely backs up important host files to a 
+#              designated mounted drive using rsync. It includes pre-run checks 
+#              to ensure the source files and destination are valid, and sends  
+#              ntfy notifications for each task.
+# Usage:       sudo ./hass_backup.sh
+# Notes:       This script may require sudo/root privileges to access files.
+# ==============================================================================
+
+# ==============================================================================
+# Define Variables for Source and Destination
+# ==============================================================================
+# This makes the script easier to read and modify.
