Things can go wrong with websites: files can get corrupted, the site can get hacked, you can delete something you don’t intend to, a server can die. Have peace of mind by having a current backup of your site.
Set up automatic backups of your site that will get sent to a storage location off your server– in case it’s your server that dies.
Depending on how often you make changes to your site, you want to have at least weekly backups, maybe daily, and save them so that you have at least a couple of weeks back — since it might be a few weeks before you realize something has gone wrong.
Remember that WordPress is a database-driven platform, so you will need the database as well as the files in your backup.
There are a number of backup plugins in the WordPress.org repository that work just fine. BackWPup has a number of nice features.
