When you have to update Drupal modules you should backup the installation files and the database. The update is not always safe and there could be unexpected side effects.
One example is with nodewords module. Half a year ago it has been updated and some features was removed and a new feature has been introduced to fill the void.Unfortunatly this feature didn't didn't work wery well.The update process have some problems too. If you plan to upgrade to a recent nodewords release, you should save the current settings.Updating a module could be dangerous. Before updating please read the forum and/or the release notes: you will avoid a lot of issues!
