Getting back to basics

Join me at my other digital home,, where I’ll go through this back-to-basics topic using a simple test—a Microsoft Windows operating system running on a virtual machine in a VMware virtual infrastructure.  I’ll cover the effects on the backup operation with each virtual disk format type and the operating system format choice.  Finally, I’ll close off with some thoughts and a discussion of HP’s Data Protector backup workflow in VMware environments when you make use of change block tracking.
