You are required to make backups of your own site. HostingCheck will not do it for you.
HostingCheck.com offers R1Soft Backup Service for $10 per month – that should be used by any customer that has a mission critical website.
Also, don't forget that HostingCheck.com does NOT provide ANY BACKUPS for any customer data. Although, we do attempt to make Backups of all shared web hosting accounts at least once per month.
These Backups are for Server Restoration Purposes only and is NOT made available to the customer. No guarantees are made of any kind, either expressed or implied, as to the integrity of these backups.
Here is the Backup Policy:
