Hyper-v virtualisation has come along way since the release of 2008 server r2, it allows for live migration of servers, this works best with clustering servers, basically 2 servers is ideal for small to medium business depending on the applications in use or the nature of the business. Which adds failsafe and failover to the equasion of failsafe data, meaning that if a server goes down, since the other server is passive and holds the same config file, this server picks up the slack of the failed server and continues to host the servers again in a space of about 1 minute, dont need to have a big san situation if cost is an issue, depending on the size of the data that a tape solution can be good enough for back up to take off site or an online facility as well for multiple locations for data recovery in a catastrophic failure.
