FAQ: Backing up virtual servers today

Experts weigh in on frequently asked questions about backing up virtual servers, including whether you need VM-specific backup software.

Introduction

A few years ago, backing up virtual machines (VMs) was performed with traditional agent-based backup software as if the virtual machines were physical servers. However, this approach left a lot to be desired. A number of virtual server-specific backup software products like Veeam emerged, addressing the challenges associated with backing up VMs, and eventually, legacy backup software vendors developed VM-backup options as well. Today, there are a variety of approaches and technologies available for VM backup. Some shops still take the traditional agent-based approach while others are using advanced functionality such as "recovery-in-place" for virtual machine data protection. If you are getting started with backing up virtual servers or you need a quick refresher on technologies available today for performing this task, this FAQ is a great place to start.
