To backup your WordPress site only takes about 5 minutes.
Go to the Admin area and select ‘Tools’ and then ‘Export’
Select what you want to Export
Select the content that you want to export. You usually will want to click on ‘All content’ as this will export all your posts, pages and any other content associated with the theme. You then click on ‘download export file’.
Find the exported file
To find the exported file, if you are on a Windows PC, right click and you can open the folder by selecting ‘Show in folder’. On a MAC go to your downloads or do a system search for the file. The saved file will be in what is called XML format.
