Yes, we do backups on daily basis of all websites hosted with us and keep them in separate server for 14 days.
If you need to access one of those backups (from the past 14 days), let us know the exact date via a support ticket and we'll get a hold of it for you.
There is no charge for that backup retrieval.
Keep in mind that we will not backup any Archive files (*.zip, *.tar, *.tar.gz, *.tgx, *.rar etc.) If you want to store your archives you can use cloud services like GoogleDrive, OneDrive, DropBOX etc.
If you wish, you can also keep your own backups localy, with plugins likeĀ BackWPup (free) and Backup Buddy (not free).

Just be aware that these backup plugins can quickly exceed your allocated disk quota if your site is on the large side - please monitor that.
