💡 Hint

Common Mistakes

Using system config directories like /etc/jenkins instead of the home directory.

The Jenkins home directory is usually /var/lib/jenkins, which contains all configuration and job data needed for backup.

2fill in blank

medium

Complete the command to create a compressed backup archive of the Jenkins home directory.

Jenkins

tar -czf jenkins_backup.tar.gz [1]

Drag options to blanks, or click blank then click option'

A/etc/jenkins

B/opt/jenkins

C/var/lib/jenkins

D/usr/share/jenkins

💡 Hint

Common Mistakes

Backing up system directories instead of Jenkins data directory.

The tar command creates a compressed archive of the Jenkins home directory /var/lib/jenkins for backup.

3fill in blank

hard

Fix the error in the restore command to extract the backup archive to the Jenkins home directory.

Jenkins

tar -xzf jenkins_backup.tar.gz -C [1]

Drag options to blanks, or click blank then click option'

A/etc/jenkins

B/opt/jenkins

C/usr/local/jenkins

D/var/lib/jenkins

💡 Hint

Common Mistakes

Extracting to wrong directories causing Jenkins to not find its data.

The restore command extracts the backup archive into the Jenkins home directory /var/lib/jenkins to restore all data correctly.

4fill in blank

hard

Fill both blanks to create a backup script that stops Jenkins, backs up data, and restarts Jenkins.

Jenkins

sudo systemctl [1] jenkins
sudo tar -czf jenkins_backup.tar.gz [2]
sudo systemctl start jenkins

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Restarting Jenkins before backup or backing up wrong directories.

The script stops Jenkins to avoid data corruption, backs up the Jenkins home directory /var/lib/jenkins, then restarts Jenkins.

5fill in blank

hard

Fill all three blanks to create a restore script that stops Jenkins, restores backup, and restarts Jenkins.

Jenkins

sudo systemctl [1] jenkins
sudo tar -xzf jenkins_backup.tar.gz -C [2]
sudo systemctl [3] jenkins

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Starting Jenkins before restore or extracting to wrong directory.

The restore script stops Jenkins, extracts the backup into the Jenkins home directory /var/lib/jenkins, then restarts Jenkins to apply changes.
