In terms of backups, databases and files, it all depends on the type of setup you choose. If you choose a server with a control panel it will make it effortless but if you want to do it manually, i suggest you take some time to learn how to do it properly, because, one error and you might loose everything you have worked for. My suggestion for a best server setup is a cloud managed cPanel VPS with SSD and good backup tool.
KVM’s popularity has been moving up on the list of virtual machine software’s due to its success with OpenStack. Marrying the 2 products together gives similar functionality as VMware vSphere, although there are some limitations with hosting Windows VMs, which are now taken care of by OpenStack’s ability to also support Hyper-V and ESXi.

– Error-proof sandbox – Virtual private servers give you “do-over” potential because they exist within a virtual sandbox. Damaging a virtual server won’t impact the operating system running on the hardware itself. “The VPS can be rebooted or reinstalled without much issue except maybe for lost data (so always keep backups),” notes Joel Lee of MakeUseOf. “On a dedicated host, a mistake could cause permanent damage.”
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
