Different from a shared hosting account where the info is backed up by the provider, if you use a virtual or a dedicated server you'll need to keep manual backups because this sort of a service is not supplied by default. As good as a hosting server may be, there's always the possibility that something could go wrong. For example, you may delete some content by mistake or a script-driven program may get corrupted after an update. If you have a backup, you shall not have to worry about this sort of issues because the content could be easily restored. As it may not be very convenient to do this regularly on your end, we offer an optional backup service for all our hosting server solutions and we will store a copy of your content on a separate hosting server to be certain that it's intact no matter what. With the upgrade, you could work on your server without worrying that you may lose any info due to any reason.
