Backup Running Hyper-V VM's using Windows Backup
The most popular question I receive is how to best perform backup/restore of virtual machines running in Hyper-V without taking them offline. The best enterprise approach is Data Protection Manager and you may have already seen some of the extensions to this functionality in 2010. But what if you have just one server at a remote site and would like to run local backups from the host?
