I have a .BAK (db backup) file and if I want to read it in Azure cloud environment, how can I read it?
Thru ADF we tried to load .bak file into Azure SQL DB, but it is not supporting. Once if we are able to load the data into any db, then we can read the data from the database.
Also tried below link, but not helping us.
How to fetch or read an .bak file in Azure data factory?
Any better recommendation or solution? Please help.
You can't use backup and restore like on-prem, you need to use bacpac export/import.
To Export (Backup)
In SSMS, right click on your-database, Task > Export Data Tier Application and follow the steps and save the file locally or on a network.
To Import (Restore)
In SSMS, connect to the azsql server, (my-azsql-server.databases.windows.net) right click on "databases" and select Import Data Tier Application and select the path to bacpac file you saved in the previous step.
Once the database is in Azure, you should be able to connect from ADF.

I've created an azure **serverless ** sql database. It seems there is no way to backup/restore this type of databases. I know there is restore to a point in time feature, But I what to download and save database backups my self.
Is there a way to backup serverless azure sql databases?
1-) There is no Backup/restore option on the database right click
2-) I've tried to use BACKUP T-SQL with azure storage account and storage url from SSMS but this is not supported.
You can use the "export" functionality by accessing the specific database in your Azure Portal to get a copy of your DB.
You can rely on Azure SQL's integrated Backup funcionality by setting up your requirements by accessing your DB Server in you Azure Portal and selecting the "Backup" uption.
You can use SSMS (SQL Management Studio), right click on the DB in question, and select "Tasks" --> "Export Data-tier Application", which will return a .bacpac file with your database. NOTE: bacpac files are not quite the same as full .bak files. bacpac files are not aware of any transactions that may be being executed whilst the data is being dumped, which means that you could end up with some data corruption.
Export your database as bacpac to an Storage Account. We are using weekly exports of the database on Saturdays, with a retention of one year for long-term backups.
The export will trigger an auto-resume of the database if the database was auto-paused.
We use an Azure Automation account and a PowerShell script to schedule the export of the database. Here you will find the script and the steps needed to schedule the script using Azure Automation.
We are new to Azure SQL Database and doing some research about the backup files. I have few questions related to SQL Database.
1) I read that Azure has built-in backup capabilities. I don't see the back up files in the azure portal. We want to use the automated backup files and restore the database in our local environments. Is there any way to access the back up files.
2) I used the SQLPackage.exe command to export the database to my local machine. With this approach it is only allowing me to export a bacpac file. Is there anyway other way to take backup files with extension of .bak
The overall goal is to take a weekly full backup and daily differential backups, which would allow us to restore the database in local. Please suggest us the best options to do so.
Thanks in advance.
We want to use the automated backup files and restore the database in our local environments. Is there any way to access the back up files.
No, you cannot access the backup files directly. In SQL Sever you can't restore a backup file to an older version of SQL Server, and Azure SQL Database is generally newer than any SQL Server you could install. So you wouldn't be able to restore them anyway.

We can see the backup on Portal: SQL Server--> Manage Backups, but we can not access the backup files and use the automated backup files to restore the database in your local environments.

For Azure SQL Database, it doesn't provide a native way to generate '.bak' format backup file. You could reference:How to create BAK file from azure sql db.
About your goal, you should using some scripts to schedule backup the database to blob, then you can use the backup to restore the database in local.
Here two ways can help you:
Powershell scripts: Backup Azure SQL Databases to Blob storage: This Azure Automation runbook automates Azure SQL database backup to Blob storage and deletes old backups from blob storage.
Tool Database Backup Tool: SQLBackupAndFTP is SQL Server, MySQL
and PostgreSQL backup software that runs scheduled backups (full,
differential or transaction log) of SQL Server or SQL Server Express
databases (any version), runs file/folder backup, zips and encrypts
the backups, stores them on a network or on an FTP server or in the
cloud (Amazon S3 and others we're constantly adding more), removes
old backups, and sends an e-mail confirmation on the job's success
or failure.
Hope this helps.
If I select to restore my Azure SQL database, I can choose from a large number of long-term backup files.
However, I just want to download those files locally.
I cannot see where I can access these files.
The Azure docs suggest that I click on the 'Manage Backups' link.
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-long-term-backup-retention-configure
I cannot see this link though.
Has anyone any idea where I can access these files?
You cannot restore those backup files to a local computer because this is a service managed by Azure.
What you can do is restore to a point-in-time which will create a new database, then export that database as bacpac to your local computer, and remove the newly created database once is no longer needed.
SqlPackage /Action:Export /SourceServerName:SampleSQLServer.sample.net,1433 /SourceDatabaseName:RestoredDatabase /TargetFile:"F:\Temp\RestoredDatabase.bacpac"
I have an App Service set up with a SQL database connection. I configured the Backup setting to backup my Web App as well as the connected database, that was all very easy, and has been running well not for a couple months. What I can't see to find is a way to get a log or report of my backup activity. If I go to the Backups blade in Azure I see the status and my backups, but there is no way to export that list. I've looked at the activity logs a bit and can't seem to find a way to query the backups to get the log. Can anyone help me out with this? I really only need a way to show the SQL database was back up, but I'm good with showing the entire App Service was back up.
There is also a log file written as part of the backup and would likely contain some useful information. To get that backup log file, from within the Azure portal, navigate to the Storage Account Container and you will see 3 files written per backup. The ZIP file which contains the actual backup, and XML file and the LOG file.
The database backup for the app is stored in the root of the .zip file. For a SQL database, this is a BACPAC file (no file extension) and can be imported. To create a SQL database based on the BACPAC export, see Import a BACPAC File to Create a New User Database.
Hope this helps.
I need to migrate a SQL Server database from Azure to AWS. I've tried to create a backup on Azure but it seems that option is not available, not even through a script.
I don't know if exists an option to backup in Azure, as you said. However, you can export your database to a .BACPAC file and import it in a local instance of SQL Server. Then you can create a .bak file from this database to export to the AWS.
To export your database to a bacpac file, you can follow this documentation:
https://learn.microsoft.com/en-us/azure/sql-database/sql-database-export
You have at least a few options here:
You can indeed create a backup in Azure. The backup file will get stored in a Storage account you set up. You can then download this and transfer it to your AWS VM (or RDS services) and restore it. I believe the manual backup you create in Azure is in the form of a .BACPAC file, which is just a compressed backup file.
You can create an empty database in AWS, sync the two schemas using something like RedGate or SSDT (which is free) and then use SSIS to move the data over. Or you could use scripts if you wanted. This would be a better option if you wanted to move your data over piecemeal.
You can use features in SSMS to copy the database directly from Azure and directly to AWS. Personally though I've never had a great deal of luck moving databases like this.
