Backing up a site is an important and often overlooked step, the reason being that it does not add or remove anything visible on the site, BUT if your host ever has a problem, or your server has an issue, or your site gets hacked, etc… a backup is a great thing to have. The plugin, Updraft Plus, allows you to set an automated back-up schedule so that you will always have your site from last week or last month to go back to immediately in case there is a disaster.
Site backups with Updraft Plus are the epitome of “set it and forget it” as the backup process happens automatically on the schedule you configure and store the backups in google drive, dropbox, email or whatever you prefer. Updraft Plus is a great plugin to install for peace of mind especially when managing a web store that needs to be back online as quickly as possible after a problem.
