Request Historical Data

When you create a Cost and Usage Report in an AWS-linked account, the S3 bucket is automatically populated with data from the beginning of the current month.

However, if the AWS account has existed for longer than this period, you can request a backfill of historical cost and usage data.

Requesting a backfill of your cost data

To request a backfill of your historical data, create a support case with AWS.

For information on how to open a support case and the information to include in your request, see the following link in the AWS Data Exports User Guide:

https://docs.aws.amazon.com/cur/latest/userguide/troubleshooting.html#backfill-data
