# Restoring a Database
|
||
|
||
---
|
||
|
||
**WARNING:** Restoring a database **replaces its current contents**. Always confirm you are targeting the correct server and database before proceeding. Close any active connections to the target database beforehand.

## Restore from a Full Backup
|
||
|
||
1. In **Object Explorer**, right-click the **Databases** node (not a specific database) and select **Restore Database…**
|
||
|
||
|
||
|
||
2. The **Restore Database** window opens on the **General** page. Under **Source**, select **Device**, then click the … (Browse) button.
|
||
|
||
|
||
|
||
3. In the **Select backup devices** dialog, click **Add**.
|
||
|
||
|
||
|
||
4. Navigate to your `.bak` file, select it, and click **OK**. Then click **OK** again to close the dialog.

|
||
|
||
|
||
5. The backup details will populate in the **Backup sets to restore** grid. Verify that the correct backup is checked.
|
||

|
||
|
||
|
||
|
||
7. Go to the **Options** page (left-hand panel). Check **Close existing connections to the destination database** to avoid connection conflicts during restore.

## Restore from a Full + Differential Backup

||
|
||
|
||

|
||
|
||
|
||
|
||

|
||

## Restoring to a Different Server or Name
|
||
|
||
To restore a backup onto a different server, or under a different database name:
|
||
1. Connect SSMS to the **target server** (not the original one).
|
||
2. Follow the restore steps in the section above.
|
||
3. At step 6, change the **Database** name field to your desired new name.
|
||
|
||
|
||
|
||
4. Go to the **Files** page (left-hand panel). You will see the original file paths listed. Check **Relocate all files to folder** and specify the data and log folders on the target server.
|
||
|
||
|
||
|
||
5. Click **OK** to restore.
