What is "CreateDBInstance:0014" and "CreateDBInstance" API operations for "RDS:ChargedBackupUsage (GB-Month)" usage type?

Question

Hi there,

I'm checking what usage in AWS is not tagged with the 3 tags I usually have (Env, Role, State) and I see the following.

Could you help me to get from where it's coming since I've all of my instances tagged and the option that copy tags to snapshot is also enabled?

Answer

The subject and body appear to be asking 2 different questions. I assume you're interested in knowing why RDS:ChargedBackupUsage is untagged. I am aware of 2 possible cases: 
1/ orphaned snapshots have no DB instance to refer to, hence no reference to instance tags either. In Cost Explorer and Cost and Usage Report, costs for RDS orphaned snapshots aggregated in a single, untagged item.
2/ Short-lived instances (less than one hour) might not get time to export tags. As a result, tags might not get applied to snapshots of short-lived instances.

If you have an AWS support option, I recommend opening a support case and support engineer can look into your AWS account and help trace those untagged charges back to specific snapshots / instances.
