CmBillingGroup Tag
At Classmethod Members, by setting the custom tag "CmBillingGroup" for cost allocation on the resources of various AWS services, you can review the usage charges for each tag in the report.
In opswitch, if the "CmBillingGroup" tag is set on source EBS volumes, EC2 instances, or other resources, this tag is automatically inherited by the created EBS snapshots, EC2 backups, or other backups. This behavior occurs automatically, regardless of the tag-copying settings for each task.
