and added the following content:

################################################################
##
## Shell script to archive website code and upload to S3 bucket.
## Written by: tutsmake
## Website: https://tutsmake.net
##
#################################################################


S3_BUCKET_NAME=""
DIR_TO_BACKUP="/var/www/html"
BACKUP_FILENAME='website'

TODAY=`date +%Y%m%d`
YY=`date +%Y`
MM=`date +%m`
AWSCMD="/usr/local/bin/aws"
TARCMD="/usr/bin/tar"

${TARCMD} czf /tmp/${BACKUP_FILENAME}-${TODAY}.tar.gz

${AWSCMD} cp /tmp/${BACKUP_FILENAME}-${TODAY}.tar.gz s3://${S3_BUCKET_NAME}/${YY}/${MM}/


if [ $? -eq 0 ]; then
 echo "Backup successfully uploaded to s3 bucket"
else
    echo "Error in s3 backup"
fi

Make sure to update S3_BUCKET_NAME and DIR_TO_BACKUP in the script. You can also change the backup file name in the BACKUP_FILENAME variable.

Then use the following command to schedule the shell script using crontab to run on a daily basis.

crontab -e 

Add the below settings to end of the file:

0 2 * * * bash /scripts/s3WebsiteBackup.sh

Save the file and close it.
