Sometimes you can face the fact that you should change your new content for the previous version of it. What can you do for being ready for this situation? Saving the whole content in the MS Word format is possible but not very comfortable method. It takes your time and resources.
For this reason there is a page versioning procedure. You just select the page you wish to backup and press the “Versions” button. The list of all page’s changes in chronological order appears. Just click the proper radiobutton and rollback the whole previous content.
If you are not sure which version of the page is the most appropriate for you needs you can use the preview mode and see every page’s version in a browser just in one click.
