Hi @Chandara. Thanks for being part of GoDaddy Community!
I don't think you would be able to create a backup using SQL Studio. We do have a process for downloading a .bak file though. For more information, please see the article here. Hope that helps. If not, feel free to provide more information. Others in the community may be able to provide you with additional suggestions.
