CREATE CREDENTIAL MyAzureBlobCredential
WITH IDENTITY = 'SHARED ACCESS SIGNATURE',
SECRET = 'your_SAS_token_here';

Step 3: Backup to Azure Blob Storage

Use the following T-SQL code to back up a database to Azure Blob Storage.

-- Backup database to Azure Blob Storage
BACKUP DATABASE AdventureWorks2022
TO URL = 'https://yourstorageaccount.blob.core.windows.net/backupcontainer/AdventureWorks2022.bak'
WITH CREDENTIAL = 'MyAzureBlobCredential',
COMPRESSION, -- Optional: compress the backup
STATS = 10; -- Optional: display progress every 10%

In this example:

  • Replace your_SAS_token_here with the SAS token generated from the Azure portal.
  • Replace https://yourstorageaccount.blob.core.windows.net/backupcontainer/AdventureWorks2022.bak with your actual Azure Blob Storage URL.
  • The WITH COMPRESSION option can be included to further reduce the backup size.

Restoring from Azure Blob Storage

To restore a database from a backup stored in Azure Blob Storage, use the RESTORE DATABASE command with the URL and CREDENTIAL options.

-- Restore database from Azure Blob Storage
RESTORE DATABASE AdventureWorks2022
FROM URL = 'https://yourstorageaccount.blob.core.windows.net/backupcontainer/AdventureWorks2022.bak'
WITH CREDENTIAL = 'MyAzureBlobCredential',
MOVE 'AdventureWorks2022_Data' TO 'C:\SQLData\AdventureWorks2022.mdf',
MOVE 'AdventureWorks2022_Log' TO 'C:\SQLLogs\AdventureWorks2022.ldf',
STATS = 10; -- Optional: display progress every 10%

In this example:

  • The MOVE options specify the locations for the data and log files on the local server.
