AWS Backup now provides customers a more seamless way to manage their backups, by automatically copying tags from their resources to their backups. For customers using tags to manage their AWS resources, AWS Backup will enable them to more effectively search for source resources or conduct billing for their backups. See AWS Tagging Strategies for tagging best practices.

Starting today, you can access custom-generated Amazon EC2 resource optimization recommendations in AWS Cost Explorer. These recommendations identify idle and underutilized instances across your accounts and regions. To generate these recommendations, AWS analyzes your historical EC2 resource usage, your Amazon CloudWatch metrics, and your existing reservation footprint to identify opportunities for cost savings (e.g., by terminating idle instances or downsizing active instances to lower-cost options). For example, if your m5.2xlarge has a maximum utilization of 20% over the last 14 days, AWS may recommended downsizing that instance to m5.xlarge or m5.large and show you how much you can save based on your usage and your applicable m5 family reservations.
