Hello Siva,
Thank you for posting your question in the Microsoft Q&A forum.
Retrieving vaulted Azure file share storage consumption details presents a significant challenge, as this information is not directly surfaced through standard Azure Backup reports or Log Analytics. The native reporting infrastructure is primarily designed to track recovery points and operational status rather than granular, historical storage metrics for individual protected items.
To obtain this data, you must implement a custom solution by leveraging the Azure Backup REST API, specifically the BackupUsageSummaries_List operation, which can provide usage details including protected items and storage consumption.
Alternatively, scripting with PowerShell or Azure CLI commands may yield these insights by querying the backup service directly. For ongoing visibility, consider integrating these API calls into a custom dashboard or workflow.
If this data is critical for cost management or capacity planning, engaging Azure support may provide guidance or reveal upcoming features intended to address this exact visibility gap within the platform's reporting tools.
