Implementing Faster Backup Compression in SQL Server 2022 🗜️

To leverage the enhanced backup compression in SQL Server 2022, you can use the BACKUP DATABASE command with the COMPRESSION option. Here’s a T-SQL example:

-- Enable backup compression (if not already enabled)
EXEC sp_configure 'backup compression default', 1;
RECONFIGURE;

-- Backup the database with compression
BACKUP DATABASE AdventureWorks2022
TO DISK = 'C:\Backup\AdventureWorks2022_Compressed.bak'
WITH COMPRESSION;

In this example:

  • The sp_configure command enables backup compression by default.
  • The BACKUP DATABASE command creates a compressed backup of the AdventureWorks2022 database.

Storing Backups in Azure Blob Storage ☁️

To back up your database to Azure Blob Storage, you’ll first need to create a Shared Access Signature (SAS) token for your storage container. Then, use the BACKUP DATABASE command with the URL and CREDENTIAL options.

Step 1: Create a Shared Access Signature (SAS) Token

In the Azure portal, navigate to your Blob Storage account, select the container, and generate a SAS token. This token allows SQL Server to authenticate and access the storage.

Step 2: Create a SQL Server Credential

Create a SQL Server credential that uses the SAS token to access Azure Blob Storage.

-- Replace with your actual storage account URL and SAS token
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.
  • Replace the URL with the actual location of your backup file in Azure Blob Storage.
