Nightly backups are made of your web hosting account using the JetBackup backup software. These are divided into full account backups; file backups; database backups; email account backups; etc.
If you need to restore your website to a previous backed-up state, then for most websites (e.g. WordPress), you will need to restore both (a) the files, and (b) the database.
To restore the website files: Go to JetBackup > File Backups, choose the date you want to restore to, click File Manager. If the website is located in the default "public_html" directory, check the box beside that name; otherwise, choose the appropriate location. Then, click "Restore Selected". Check the warning box that appears, and click "Add to Restore Queue".
To restore the database: Go to JetBackup > Database Backups. If more than one database exists for each date, you need to know which database is used by your website (if you are not sure, and it's running WordPress, you can open the file wp-config.php to find out). Once you have determined the correct database, choose the one corresponding to the date you want to restore to, then click Restore. Check the warning box that appears, and click "Add to Restore Queue".
Now, you can monitor the progress of the restoration by going to JetBackup > Queue. Once the Status column shows "Completed" for all tasks, then the restore has been finished.
Browse to the website to verify it appears as it should.
Want an easier way to manage WordPress backups?
If your website runs WordPress, then go to the "WP Toolkit" section of cPanel. There, you will find the ability to create a point-in-time snapshot of the WordPress website, which then allows a single-click restore to that point in time. This is quicker and easier than using the hosting account's nightly backups, for situations where you are planning an update and know you may require the use of a backup ahead of time.
