It is a known fact that Jenkins always requires some disk space in order to execute the build jobs and archive the same. This is configured by using the JENKINS_HOME. This path can be configured whenever required.
In Jenkins, all the settings, build logs and archives of the artifacts are stored under the JENKINS_HOME directory. The easy way is to just keep this folder separately as a new back and whenever the same needs to be used, just copy it back.
The build jobs created under this directory contains all the details of each and every individual jobs configured in the Jenkins install. Any job can be moved from one installation directory to another just by copying the jobs.
Also, Jenkins provides the feature of renaming an existing job on the fly. To reflect the applied changes, just click on the reload config from the user interface of the Jenkins.
Sometimes there may be some build jobs which remains unused for a longer time. In that case, there is an easy way to archive the same. Just navigate to the JENKINS_HOME directory and create an archive folder for the job which needs to be archived.
Since, Jenkins can be enormously extended by the usage of several plugins, there comes a plugin which can be used for the backup management in Jenkins - ThinBackup plugin. This plugin backs up the job specific configuration files.
