Read these steps carefully to Backup Restore MySQL Database

Step 1: Create a MySQL Database Backup

1. Open phpMyAdmin. On the directory tree on the left, click the database you want to back up.

This should open the directory structure in the right-hand window. You’ll also notice that, in the directory tree on the left, all the assets under the main database are highlighted.

2. Click Export on the menu across the top of the display.

You’ll see a section called “Export Method.” Use Quick to save a copy of the whole database. Choose Custom to select individual tables or other special options.

Leave the Format field set to SQL, unless you have a good reason to change it.

3. Click Go. If you select Quick, your web browser will download a copy of the database into your specified downloads folder. You can copy that to a safe location.

Step 2: Clear the Old Database Information

It’s important to clear out old data before restoring a backup. If there’s any old data, it isn’t overwritten when you restore. This can create duplicate tables, causing errors and conflicts.

1. Open phpMyAdmin, on the navigation pane on the left, choose the database you want to restore.

2. Click the check all box near the bottom. Then, use the drop-down menu labeled With selected to select Drop.

3. The tool should prompt you to confirm that you want to go forward. Click yes.

This will get rid of all the existing data, clearing the way for your restoration.

 

Step 3: Restore Your Backed up MySQL Database

In phpMyAdmin, the Import tool is used to restore a database.

1. On the menu across the top, click Import.

2. The first section is labeled File to import. A couple of lines down, there’s a line that starts with “Browse your computer,” with a button labeled Choose File. Click that button.

3. Use the dialog box to navigate to the location where you’ve saved the export file that you want to restore. Leave all the options set to default. (If you created your backup with different options, you can select those here.)

4. Click Go.
