How Do I Back Up My Site Using the Updraft Plus Plugin?
UpdraftPlus is a popular plugin used to back up WordPress sites. There is also an add-on that allows you to migrate a site very easily (in most cases).
Pros: works with a lot of sites and hosting companies, easy to connect to remote storage (and video instructions at their YouTube Channel), a video tutorial to show you how to do backups (below).
Cons: instead of a complete back up, you have download individual files for the theme, uploads, plugins and database which feels time consuming (you can avoid this by connecting it to remote storage).
