Our servers are configured to create a daily, weekly (sunday) and monthly (1st and 15th of each month) backup.
But we strongly suggest that you create your owns backups.
You can backup your site by login to your cpanel at https://cpanel.yourdomain.com
The server backup service for your site is free but can only be triggered by the administration.
Open a trouble ticket and request the restore of your site if ever your personal backup is corrupted or worst, you have forgot to set one and we will restore your site with all datas (including mysql, accounts, etc) with the last one we have on records for your site..
As said the service is free but not monitored, we do NOT garantee the backup will be 100% reliable or usable and all datas will be there.
It is your responsibility to make your own backups and check the reliability of the restore backups.
