Actually Groupee manages the forum server and it's including data. So Groupee is responsible for the safety of the backups. Ubisoft had probably choosen for Eve because it's remotely hosted, which means that Groupee mananges the system updates and the data, so that Ubisoft doesn't have to spend all day to take care of that. But even in remotely hosted forum software solutions, there are better choices than Eve, think about Lithium or JiveForums, both used by companies like Nintendo and Sony.
