Hi @milan i ,
You can using a third part tool Hevo Data , a fully managed and automated tool. Or you can also using a third part tool Skyvia . Skyvia allows you to set a schedule for a package to execute it automatically. This might be useful if you want to configure data loading operations to run periodically or if you want to delay an operation to a later time.
You can also Export Data from Salesforce to SQL Server using Export and Import Wizards, but you need to do this manually.
Refer to below blogs to get more detail information;
