Backfill cost allocation tags
Management account users can request a backfill of cost allocation tags for up to twelve months. When you request a backfill, the current activation status of the tags are backfilled for the duration of your choice.
For example, the Project
tag was associated to an Amazon Resources in June 2023 and activated in November
2023. On December 2023, you request to backfill the tag from January 2023. As a result,
the Project
tag is retroactively activated for the prior months from
January to December 2023. The tag values associated to the Project
tag will
be available with the cost data from June 2023 to December 2023. However, January 2023
to May 2023 will not have tag values associated because the Project
tag was
not present in the Amazon Resources.
Backfill can also be used to deactivate tags for alignment. For example, a Team
tag was active in prior months, but currently is set to inactive
status. Backfilling will result in the Team
tag being deactivated and removed from the cost data for previous months.
Note
The resource tag must be historically assigned to the Amazon Resource for the backfilled cost data to be available.
You can't submit a new backfill request when there is a backfill in progress.
You can only submit a new backfill request once every 24 hours.

Updating your Amazon Cost Management services with backfill
Backfill will update your Cost Explorer, Data Exports, and Amazon Cost and Usage Report automatically. Because these services refresh your data once every 24 hours, your backfill won't update as soon as it succeeds. For more information, see the following resources in their corresponding guides:
