At D9 Hosting we automatically back up your files on weekly basis. However, we always advise our Clients that they should not rely on these backups alone, Clients should always perform their own regular back ups and store them on their own local machine or offsite backup storage space.
D9 Hosting allows you to manually back up and download all your files, selected files or MySQL databases through your cPanel -- follow our step-by-step video tutorial found in our cPanel Video Tutorials in your Client Area (Video 3)
