If you are a blogger or a site owner who has invested enough time and resource to get things going, then you know how important it is to back up your content on a regular basis. This ensures that you don’t lose much or any of your data if you are hacked or compromised in any way.
Backing up your WordPress site is something you should take very seriously. If your site gets hacked or you somehow get locked out, you will have no other option but to rely on your backups to get your site back up and running the way it was.
These backups can be managed and stored in various ways. You can do them manually or use an automatic service that does it for you. In turn these backups can be stored on your computer or on some other storage service such as Dropbox.
It doesn’t matter how careful you are. At some point of another, a plugin is going to cause your WordPress website to crash. The only way to avoid a crash is to have a test area that is an exact clone of your live website; with the same plugins, posts, pages and theme. Whilst I am a strong advocate of actively using a test area to try out new plugins and changes, I do not believe it is practical to keep an exact duplicate of your live website, particularly if that website has a lot of content. So realistically, you’re going to have to deal with a problematic plugin in the future.
