If you have a backup of a MySQL database saved as an uncompressed .sql file or a compressed .sql.gz, .tar.gz or .tgz file, you can restore that database to your cPanel account fairly easily. Here's how to do it:

  1. Log in to your cPanel: https://YOURDOMAIN.com/cpanel
  2. Click on “Backup” under the section Files.
     
  3. Under “Restore a MySQL Database Backup”, click on the “Choose File” button.
     
  4. Select your sql, sql.gz, .tar.gz or .tgz file to restore.
  5. Click “Upload” and be patient. Larger backups may take some time to finish restoring.

Please be aware that cPanel will only restore things that your cPanel account is permitted to use and may strip out advanced permissions. Also very large or corrupted backups may not restore properly.

If the backup is too large to restore via cPanel, you may want to try BigDump, which uses PHP to try to import large sql files a little bit at a time.
