Unlike a shared hosting account where the info is backed up by the provider, when you use a virtual or a dedicated hosting server you will have to keep manual backups as this kind of a service isn't provided by default. As good as a server could be, there's always a possibility that something could go wrong. For example, you might delete some content by accident or a script-driven app might get corrupted after an update. In case you have a backup, you shall not have to worry about this kind of issues as the content can be easily restored. Considering that it may not be really practical to do this all the time on your end, we provide an optional backup service for each of our server plans and we shall store a copy of your content on an independent server to make sure that it is unharmed no matter what. With the upgrade, you'll be able to work on your hosting server without needing to worry that you could lose any info due to any reason.
