Earlier when upgrading a WordPress site that is running on a CentOS Linux server I needed to quickly backup the entire site to then perform an upgrade of the core WordPress installation. There are multiple directories located beneath the primary site folder that I didn’t need to backup including some caching directories as well as a database backup directory since all of those directories are not required to restore the site in case of an issue during the WP upgrade. Use the information below to create a tar archive while excluding multiple sub directories.
On a recent installation of PostgreSQL on CentOS Linux I had some issues after making some configuration changes. I have a basic template of changes I make to Postgres after initial installation and then I restart the PostgreSQL server. This time when restarting Postgres it failed as shown below.
