As of now, WordPress is powering 48 of the top blogs on the Internet. Aside from that, WP can also be powering 19 percent of the web as a whole. It means that a lot of people trust WordPress when they want blogs and creation of sites.
I back my blogs using a free plugin WP DB Backup up. I will restore my blog if anything happens. I use WP Security Scan plugin that is free to scan my site and WordPress Firewall to block asks that are suspicious-looking to fix wordpress malware virus.

I prefer using a WordPress plugin to get the work done. Make sure is able to do copies, has restore and can replicate. Be sure it is frequently updated to keep pace with all versions of WordPress. There is no use in not functioning, and backing your data up to a plugin that is out of date.
