Hi Daniil Trishkin , Thanks for posting your query on Microsoft Q&A.
Azure DICOM service is a managed service that ingests and persists DICOM objects at high speed and facilitates communication with any DICOMweb™ enabled systems or applications.
To export data from the DICOM service, you need to enable a system managed identity and give permission to the storage account used as the destination for export. You can use the export API of the DICOM service to specify the criteria for selecting and exporting DICOM files.
As for retention policy, Azure does not provide any specific retention policy for customer data stored in its services. Customers are responsible for identifying their own record retention requirements and extracting their data outside of Azure for a customer-specified retention period, more details here.
You can use Azure Blob storage lifecycle management to automatically transition your blob data between tiers based on your defined rules.
I hope this helps you understand the possibility of using Azure DICOM service and data archiving.
