# Database Manager on Windows hosting: open and import databases

> Open Database Manager for your HyperDC Windows hosting databases from the client area, sign in with the database login and import .bak, .sql and data files.

Difficulty: Intermediate

**Database Manager** is web-based database management for the SQL Server and MariaDB databases of your Windows hosting service. You open it from the client area; it runs at your own domain.

## Open Database Manager

1. Open **Databases** on your service page and select **Database Manager** next to the database. You can also use the link under **Connection details** on **Overview**.
2. Sign in with the database's own login and password, not your client area login.

It opens at `https://dbadmin.example.com/`, with your own domain in place of `example.com`, once your domain points to the server. You see the objects of your own database; other customers' databases stay out of sight.

## Import data

Database Manager imports these files into your database:

| File | Use it for |
|---|---|
| `.bak` | A SQL Server backup, also one made on another server |
| `.bacpac`, `.dacpac` | A SQL Server data-tier export or package |
| `.sql` | A script of tables and data; one made for another database name is converted to yours |
| `.csv`, `.tsv`, `.json`, `.xlsx` | Table data from text, JSON or Excel files |

To import a file you already uploaded to your hosting, open Database Manager from the client area: then it can read files straight from your hosting folder.

> **Warning**
>
> An import changes the data in your database. Export a copy first if you may need the current state.

**Verify:** the tables you imported appear in the database with the rows you expect.

## Export a backup

Database Manager does not export `.bak` files. For a SQL Server database, use **Export** in the database's menu in the **Databases** tab; see [databases on Windows hosting](/guides/windows-hosting-databases).

## Troubleshooting

**Login failed.** Use the database's login and the password you set when you created it.

**The Database Manager address does not open.** Your domain must point to the server first; see [point a domain to your server](/guides/point-domain-to-server).

## Frequently asked questions

### Which login do I use?

The database's own login and password, not your client area login.

### Can I bring a database from another server?

Yes. Database Manager imports .bak, .bacpac, .dacpac and .sql files, and table data from comma or tab separated text, JSON and Excel files. A .sql file made for another database name is converted to yours.

### Can I export a .bak file here?

No. Use Export in the Databases tab of your service page; see databases on Windows hosting.

### Can other customers see my database?

No. You see only the objects of your own database.
