What are the ways to duplicate a site with a database online?

Question

Backup

Good afternoon
I encountered such a problem for 10 hours one hoster did not work and, accordingly, my site did not work. Since the site is visited, the mail received a lot of indignation from visitors.
And I thought that if I had stored a duplicate of the site on another hosting, then by changing the IP in the domain records, the site could be restored in a few minutes. Is there any way to make a copy of the site online? The site is updated almost every minute by users (files and records in the database)
