UpdraftPlus is the backup plugin that a lot of WordPress site owners install on day one and then forget about, which is exactly how a backup plugin should work. It backs up your files and your database, either on a schedule you choose or when you press the button, and it sends the backup to somewhere safe: Google Drive, Dropbox, Amazon S3, or a dozen other places, including plain email for small sites. If something goes wrong — a bad update, a hacked site, a host that loses your files — you can restore from the backup in a few clicks from the WordPress admin, without needing to know how databases work. You can also download a backup and move a site to a new host with it, which is how a lot of people migrate sites. The free version covers the essentials: scheduled backups, remote storage, and one-click restore. It is a small plugin for a job that matters a lot, and it is the first thing to set up on any site you care about.
