restore under RHEL 7












1















Say there's an application that install to /opt/ directory. I update it with yum. I do a full server backup, that is all the file systems (/opt/ maps to the root directory). Now, I discover a bug post upgrade or have the need for whatever reason to restore to the pre upgrade state. Should I:



a) restore the whole /opt/application directory along with its files and sub-directories;
b) perform a complete system restore to the last backup
c) or perform a yum roll back How to use yum history to roll back an update in Red Hat Enterprise Linux 6 , 7?

          Use yum (or dnf in RHEL-7) to roll-back (remove) the application. This keeps the package repository consistent with the software installed.

          • Ok but what if the update made also changes to a MySQL DB on a remote server ? Doing a yum roll-back will not revert the changes made to the DB, right ?

          • Correct. The rollback is for the software package.

          • Thank you. So I'd would have to perform a yum roll-back + a DB restore to get the previous good know state?

            Yes, the yum/dnf rollback takes care of the software. You need to deal with the database independently.
