Description

Virtual Machine (VM) snapshots enable you to revert a VM to a previous state. A Hyper-V snapshot contains all the state information for a running host VM and use differencing disk AVHD files that reference the original VHD and the memory state if the VM is running.
When considering a backup strategy for a Hyper-V environment, you must consider the host OS partition, the host data partitions containing the VMs, and the contents of each hosted VM. System Center Data Protection Manager (DPM) 2010 is a streaming backup solution to offer continuous backup that’s part of the System Center suite of management tools. DPM remotely captures VSS images and streams them to a central disk repository.
Hyper-V VM migrations are performed in System Center Virtual Machine Manager. Three basic migration types are available – network migration, quick migration and SAN migration. Live Migration is a new feature of Hyper-V R2. Live Migration avoids the downtime associated with other migration types by transferring the memory state over the network in real-time.
This course describe how snapshots and backups enable VM recoverability to a previous good state. The various strategies exist to migrate a VM from one host to another, even with near zero downtime are also covered.
