SQL SERVER – SQL Server Management Studio Crash While Using Backup to URL or Connecting to Storage

Recently, as a part of my on-demand consulting, I was helping a client who was into a disaster situation and there was an urgent need to restore the backup of a database which was taken in Azure Blob Storage. In this blog, we will learn about how to fix the crash of SQL server Management studio while using a backup to URL or connecting to storage.

As explained earlier, the client was trying to restore the database backup which was stored in Azure blob storage. They were going to “Restore Database” menu option in SSMS, choosing the device as URL. As soon as they click on the add button, SQL Server Management Studio was crashing. Here is a screenshot.

Above information could not help in finding the cause but I have shared here so that someone can search and reach to this blog.

Then I tested the same steps on my SQL Server Management Studio and it was asking to connect to a storage account from where the backup can be picked for restore purpose. So, I asked my client to connect to storage directly by using SQL server Management studio using the below option.

Strangely, we could see the same crash of SQL Server Management studio there as well. This test confirmed that there is some issue with the information stored by SQL Server Management Studio about the storage account. My client has been using the same SSMS and in the past, he was able to connect to Azure storage.


I have asked my client to use some different machine and try to connect to the Azure storage from that machine. Interestingly, it worked, and it confirmed our theory.

Now we need to figure out, how to clean up the information stored about storage account in the cache of SSMS. I was not able to figure out the way to clean up only Azure storage-related information from the user profile. So, I ended up in removing complete saved settings of SSMS by deleting a sqlstudio.bin file from %appdata% user profile. This file “sqlstudio.bin” is located under below location. (Go to Start > Run and paste the below path)

%AppData%\Microsoft\SQL Server Management Studio

Once the folder is opened on your server, you might see a folder like below.

Based on the SSMS version, go inside the folder and delete “sqlstudio.bin” file. (You can also rename the file and SSMS would create a new one).

NumberSQL Server Management Studio (SSMS) Version
11.0SQL Server 2012
12.0SQL Server 2014
13.0SQL Server 2016
14.0SQL Server 2017
18.0SSMS 18.0 (separated from SQL Server)

Please keep in mind that, this is not smartest solutions available as it would delete all saved information in SSMS (like username password, server names list, any settings which you have changed etc.)

    The above solution did not work for me.

    I am using SQL Server Management Studio 18.0 Preview 4 and database which I am trying to restore is of same SQL Server instance..Microsoft SQL Server 2016 (SP2) (KB4052908) – 13.0.5026.0 (X64)

    I get the error when I click on Options menu in the Restore Database screen after I have selected the .bak file.

    Just downloading the latest SSMS 18.4.. May be that might do the trick..

    I will update on the workaround.
