Historical data updates are all handled differently based on the cloud provider:
AWS
If CUR Refresh setting is enabled, CloudHealth is looking for changes in all 13 months every day. The platform does not lock months. If CloudHealth detects a change in any of the previous 12 months, an update will be made within the platform.
Azure
CloudHealth will collect the previous month and the current month every day until the 10th of the current month. After the 10th, only the current month will be updated daily. The previous month will be locked after the 10th. A request can be made to refresh of locked months via support ticket.
GCP
CloudHealth will recollect GCP changes up to 60 days back. If a change is detected in that 60 day window, the plaform will collect the data and make the update in CloudHealth. A request for a refresh of locked months can be made via support ticket.
