In contrast to a shared web hosting account where the info is backed up by the service provider, when you use a virtual or a dedicated web server you will have to keep manual backups since such a service isn't included by default. As good as a web server might be, there's always a chance that something might go wrong. For instance, you can delete some content by mistake or a script-driven program may get corrupted after an update. In the event that you have a backup, you will not need to bother about this kind of problems as the content can be easily restored. As it may not be quite handy to do this regularly on your end, we supply an optional backup service for each of our web server plans and we'll store a copy of your content on a separate hosting server to ensure that it is unharmed no matter what. With the upgrade, you could work on your web server without worrying that you might lose any information due to any reason.
