Why is it beneficial for a CI server to have access to a trustworthy backup in a distributed VCS?

Access to a trustworthy backup allows a Continuous Integration (CI) server to quickly access the latest changes made to the codebase. In a distributed Version Control System (VCS) like Git, every developer has their own complete copy of the repository, including all its history. However, a CI server needs to have a reliable source of the latest state of the code to build, test, and ensure integration works smoothly. When the CI server has access to backups, it can restore to the most up-to-date version swiftly in the event of an issue or failure, ensuring that the integration process is not hindered by data loss or corruption.

This rapid access to the latest changes facilitates continuous feedback for developers, allowing them to identify and address issues as they arise. Furthermore, trustworthy backups enhance the resilience of the CI/CD pipeline, ensuring that operations can continue even in the event of hardware failures or other disruptions. By maintaining an up-to-date backup, the CI server can operate efficiently, driving productivity and enhancing the overall developer experience.
