How I can submit the support ticket to restore the corrupted data in Cosmos DB?

Question

I accidentally deleted the items in the container. When I tried to submit a support ticket, I couldn’t reach anyone. It appears that Developer Support has not offered technical assistance since 6 February 2025. I’ve already switched the backup policy from periodic to continuous; previously, the retention period was seven days and 42 versions of the data were kept. May I send the restoration details to you in a private message?

Hello Dikaver,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you are asking on how you can submit the support ticket to restore the corrupted data in Cosmos DB.

You should have submitted the request within 8 hours of the deletion or corruption to maximize the chances of successful recovery.

However, you mentioned Developer support hasn’t offered assistance since February 2025. If that’s the case, and you're unable to submit a ticket through the portal, I recommend:

• Upgrading to a Standard or Professional Direct support plan via the Azure Support Plans page.- https://azure.microsoft.com/en-us/support/plans/
• Or contacting Microsoft directly via Azure Support Contact.- https://azure.microsoft.com/en-us/support/

If You are now on Continuous Backup, you can restore data yourself using the Azure Portal: The below is a Step-by-Step: Self-Service Restore Continuous Backup

1. Go to Azure Portal: https://portal.azure.com
2. Navigate to your Cosmos DB account
3. In the left pane, select “Point In Time Restore”
4. Provide:
   • Restore Point UTC: The timestamp before deletion
   • Location: Region where the account existed
   • Restore Resource: Choose entire account or specific container
   • Resource Group: Must already exist
   • Target Account Name: A new name for the restored account
5. Click Submit to begin the restore - https://learn.microsoft.com/en-us/azure/cosmos-db/restore-account-continuous-backup.

NOTE: You must have the Microsoft.DocumentDB/locations/restorableDatabaseAccounts//read permission - https://learn.microsoft.com/en-us/azure/cosmos-db/restore-account-continuous-backup.

Secondly, if you still need to submit a support ticket

1. Go to: Create Azure Support Request- https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request
2. Choose:

• Issue Type: Technical
• Service: Azure Cosmos DB
• Problem Type: Data Recovery

3. Provide:

• Subscription ID
• Account, database, and container names
• UTC timestamp of deletion
• Whether a new container was created
• Whether you want isolated restore

CAUTION: You must have a Standard or higher-tier support plan to submit this request- https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request . If any of the above information is not available. opt for similar.

I hope this is helpful! Do not hesitate to let me know if you have any other questions or clarifications.
