Backup and deploy with shell script

I have a productive environment for which I upload html, css etc. files. However, every time I upload a file I must first back up existing instances.

I'm trying to build a script that does the following:

Read the upload directory and search for production if that file exists, if you do a backup
Copy the files for production and generate a list (txt) of the copied files
In case you need to back up, I need the script to remove everything that was copied (to remove new elements if they exist) and copy back the backup files

However, I'm pretty much lost once shell script is not my strong. Would anyone have any idea how to produce this script?

I currently have this snippet of code:

#!/bin/bash

if [ ! $1 ]
then
        echo "Informe o nome do diretorio de upload"
        exit 0
fi

DirUpload=/home/upload/$1
DirProducao=/home/producao


cd $DirUpload
find . | sed 's/\.\///g' > upload.txt

for i in 'cat $DirUpload/upload.txt'
do
        if [ -d $DirProducao/$i ]
        then
                echo "Diretorio: ${i}"
        elif [ -f $DirProducao/$i ]
        then
                echo "arquivo: ${i}"
        else
                echo "nao encontrado ${DirProducao}/${i}"
        fi
done

By now I'm using the above script to generate a txt with the list to load, based on it I'm checking what currently exists in production to be able to copy to the backup

This script will help you, you can edit it at will:

#!/bin/bash

# Pasta Backup
backup="/home/arcadian/workspace/works/backup"
#Pasta Prod
prod="/home/arcadian/workspace/works/prod"
#Pasta Upload
upload="/home/arcadian/scripts/shell"
#Arquivo txt
txt="/home/arcadian/copiados.txt"

main(){
# Funções, basta comentar pra usar a que deseja.    
deploy
rollback
}

deploy(){

if [ -e $txt ];then
    rm -f $txt;
fi

    for i in $(ls $upload); do
    for a in $(ls $prod); do
        if [[ $a == $i ]];then
            cd $prod
            cp $a $backup
            ls $a >> ~/copiados.txt
            cp -rf $upload/$i $prod
        fi  
    done
done

rollback(){
for i in $(cat $txt); do
    rm -rf $prod/$i
    cp -rf $backup/$i $prod
done
