Hello,
I studied the job description and I can help you to take Centos 7 server backup to S3. Please provide me root login details for the server and WHM.
As I am expert with Server administration and highly skilled with Linux, CentOS, Cpanel, WHM, Digital Ocean, CentOS7, AWS AWS S3, AWS Ec2, MySQL, PHP etc. I already worked with this kind of projects.
I look forward to communicate with you.
Thanks
