Yum source backup

Yum source backup refers to the process of creating a copy of the default Yum repository configuration file before modifying system sources.^[600-developer-docker-yum-aliyun.md]

This is a standard preliminary step in system maintenance, particularly when switching to a different repository mirror, such as Aliyun.^[600-developer-docker-yum-aliyun.md]

Procedure

The default repository file is located at /etc/yum.repos.d/CentOS-Base.repo.^[600-developer-docker-yum-aliyun.md] To create a backup, the mv (move) command is typically used to rename the original file to CentOS-Base.repo.backup.^[600-developer-docker-yum-aliyun.md]

The command to perform this action is: 

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
