You can roll a MySQL database back to an earlier copy with JetBackup.
Restoring a Database
- Log in to cPanel (see How to Log In to cPanel)
- In the JetBackup section, click Database Backups
- Find the database and choose a backup from a date before the problem
- Click Restore and confirm
Follow its progress under Queue.
Restoring a database replaces everything in it. Any orders, comments, posts or form entries since that backup will be lost. Export a copy first with phpMyAdmin if you might need them.
Which Database Is My Website?
For WordPress, open wp-config.php in File Manager and look for the line with DB_NAME.
