MAX_BACKUPS=3  # Maximum number of backups to keep
JELLYFIN_SERVICE="jellyfin"  # Jellyfin service name

# Timestamp format YYYYMMDD_HHMMSS
TIMESTAMP=$(date +"%Y%m%d_%H%M%S")
ZIP_FILE="$DEST_DIR/Jellyfin_backup_$TIMESTAMP.zip"

# Ensure destination directory exists
mkdir -p "$DEST_DIR"

# Stop Jellyfin before backup
echo "Stopping Jellyfin service..."
