Hello again folks! Today I wanted to talk a little bit about virtual machine backups. When backing up in a virtual environment there are two types of backups you are looking at. File level backups and virtual machine level backups.
File level backups are self explantory, they are the backups you run with backup software to backup the individual files, folders and system state data on a server. Everyone should already be doing these kinds of backups.
Virtual machine level backups are backups of the entire virtual machine itself. Virtual machine backups consist of the actual files that make up the entire virtual machine. For example in the case of VMware, the vmdk and vmx files for example. By backing these files up, you can restore the entire virtual machine to another location if your ESX server and the storage area that holds the virtual machine blows up. You can install a new ESX server and restore the entire virtual machine to a new storage location managed by a new ESX host.
One of my favorite products to do this is the free script from William Lam called GhettoVCB. You can read more details about it in my post here.
