This is a quick example of how to restore a MySQL database dump of a single database.
WARNING: This restore process may overwrite your database by the backed up copy you are restoring.
Step 1
Create a MySQL backup for sampleDatabase
(as an example).
Step 2a
Go to your backup page, then select the "Logs" tab. Afterwards, click the little "( i )" on the right next to the copy you want to download.

Step 2b
Under the backup restore section on the modal that just popped up, click on "Click to generate a signed download link" then copy the resulting link
Step 3
On your server, run the following command, and use the signed download link you obtained in the previous step (ensure you enclose it in double quotes as shown):
wget "PasteTheSignedDownloadLinkHereBetweenTheQuotes" -O "mysql-backup.sql.gz"
Step 4
Now that you downloaded the database backup on your server, extract it as shown:
tar -xvf mysql-backup.sql.gz
This will output a single SQL file in this format db-backup-XXX.sql
in the same directory.
Step 5
Note: the following command will overwrite your sampleDatabase
by the database copy you are restoring. It is a good practice to inspect the backup first before the restore.
Restore and overwrite your by the downloaded backup as shown below by running:
mysql -uYOURDATABASEUSERNAME -pYOURDATABASEPASSWORD < db-backup-XXX.sql
