Back Up and Restore Virtual Machines

A good backup strategy is the last line of defense against disasters such as hardware failure, environmental damage, accidental deletions, or misconfigurations. In a virtual environment, a backup strategy can turn into a daunting task because of the number of virtual machines that need to be backed up. In a busy production environment, a new virtual machine can come and go anytime. Without a proper backup plan, the entire backup task can become difficult to manage. Gone are the days when we had only a little server hardware to deal with and backing it up was an easy task. In today's virtual environments, a backup solution has to deal with several dozen, or possibly several hundred, virtual machines.
