Jenkins Backup & Restore

Jenkins is a powerful tool for Continuous Integration and Continuous Deployment (CI/CD). As with any critical system, ensuring that your Jenkins setup is backed up and can be restored is essential.

Why Backup Jenkins?

Backing up Jenkins is crucial for several reasons:

• System Failures: Hardware or software failures can occur, and a backup ensures you can quickly recover.

• Human Error: Mistakes can happen, such as accidental deletion of jobs or configuration changes.

• Upgrades and Migration: When upgrading Jenkins or migrating to a new server, having a backup helps prevent data loss.
