In contrast to a shared hosting account in which the info is backed up by the hosting company, if you use a virtual or a dedicated web server you will have to keep manual backups since such a service is not supplied by default. As good as a hosting server may be, there's always a possibility that something may go wrong. As an example, you may delete some content by mistake or a script-driven app could get corrupted after an update. In the event that you have a backup, you'll not need to worry about this sort of problems since the content could be easily restored. As it may not be really handy to do this all the time on your end, we provide an optional backup service for all our web server packages and we will store a copy of your content on an independent server to be certain that it's unharmed no matter what. With the upgrade, you could work on your server without having to worry that you might lose any data due to any reason.
