It is a good practice to backup all the environments in your workflow/pipeline. For example, backing up the metadata in your developer sandboxes would provide a version history of the changes made in the sandbox and allow for rollbacks in the event of an error.

Copado Essentials Plus (the premium edition of Copado Essentials) can perform a back using the steps outlined below. This will require a CI Job with a webhook for each environment and a configuration of a "Backup" repo with your Git provider.
​
1) Configure a "Backup" repository with branches for each environment in your workflow:
​
2) Set up your CI Jobs for each environment you would like to have backed up.

For details on how to configure a CI Job to deploy all changes since the last successful deployment, see this article.

Note that there is a limit on the maximum number of CI Jobs per Essentials team.
