Hosted by Evolve Systems:

If your website is hosted with Evolve Systems, then your website is automatically backed up each day. If you would like to back up the site yourself, you need to contact us via the Help Desk to request access to your site portal. Once you have access to your site portal, you can click on Backup Points to create a backup. Directions can be found here.

If UpdraftPlus is installed on your site, click on UpdraftPlus in the top navigation menu. From there, click on backup now and follow the prompts. You can add UpdraftPlus by searching for it under the plugins section.
