Backups are automatically created weekly on the Premium plan and daily on the Business plan. You can save backups to your PC by going to Control Panel - Backups. To restore files from backups to the public_html folder, go to Control Panel - Import Site.
You can also extract files to your PC and upload them to hosting using an FTP client (for example FileZilla). FTP connection details can be found in Control Panel - FTP Access. To import the database use phpMyAdmin tool - Import.
If you do not have a backup, do not worry, contact technical support and we will check your backups on our servers!
