You are responsible for your backups and web content.
You can create your own backup in the hosting control panel for free. We create our own backups on the shared servers, and we can restore from those if we have yours available. We only have server wide backups from the last week or month.
However, this is NOT a procedure you should rely on to keep your content safe. Backups are kept for 3 days. We require a $15 fee to reupload, restore and reactivate the backup. If you can provide your own backup file, then the fee is $0 (free).
