Regarding Control Hub Cloud and the logs retention policy, here is what we know so far:
1- Is there an audit log telling who deleted which pipelines?
- No, but Adam has created a repo (https://github.com/kunickiaj/action-streamsets-control-hub) we can use to automatically back up pipelines on every commit to a git repo.
2- in Cloud, do we retain logs for groups (changes, erasing, etc.?)
- No, only audit logs are for user login / password change
