If the instance is a production instance, has automated backups enabled, and has less than 21 retained backups, it is recommended to increase its backup retention.\n\nRecommendations are generated daily.\n\nPricing\n-------\n\nThe Cloud SQL increase backup retention recommender is in the *Standard* [Recommender pricing tier](/recommender/pricing).\n\nBefore you begin\n----------------\n\nBefore you can view recommendations and insights, do the following:\n\n- To get the permissions to view and work with insights and recommendations, ensure that you have the required [Identity and Access Management (IAM) roles](/sql/docs/mysql/project-access-control#roles).\n\n For more information about IAM roles, see [IAM basic and predefined roles reference](/iam/docs/understanding-roles) and [Manage access to projects, folders, and organizations](/iam/docs/granting-changing-revoking-access).\n-\n\n\n Enable the Recommender API.\n\n\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=recommender.googleapis.com)\n\nList reliability recommendations for increasing backup retention\n----------------------------------------------------------------\n\nYou can list the increase backup retention recommendations by\nusing the Google Cloud console, [gcloud CLI](/sdk/gcloud), or the Recommender API. \n\n### Console\n\nTo list increase backup retention recommendations using the\nGoogle Cloud console, follow these steps:\n\n1. Go to the **Recommendation Hub**.\n\n [Go to the Recommendation Hub](https://console.cloud.google.com/home/recommendations/)\n\n For more information, see\n [Getting started with Recommendation Hub](/recommender/docs/recommendation-hub/identify-configuration-problems).\n2.
