We're in le middle of P2V'ing le plus of le network, so le current backup method is likely le worst - le backup agent is encore installed on le guest OSs, et le backup device is dutifully pulling them onto tape, one file at a time.
I suspect il y a a clever way to script (PowerShell?) a suspend on le VMs, alors backup of le .vhd files, et unsuspend le VMs. This seems like it would provide big speed benefits, tandis que losing file-level restore (might be best for things like DCs et app servers).
What methods/policies have you hammered out?
Meilleures méthodes pour sauvegarder les VM exécutées sur Hyper-V
Re: Meilleures méthodes pour sauvegarder les VM exécutées sur Hyper-V
Regular file-level backup of seulement data should encore be used - regardless of si le machine is virtual ou not. Backing up le disk file however is a great aid in increasing recovery speed for disasters si le entire guest fails.
Il y a plusieurs approaches to backing up le guests avec scripting. You could [shut it down](http://bunkerhollow.com/blogs/matt/archive/2008/09/24/hyper-v-vm-backup-script-batch-file.aspx), copy le vhd et start it again. A clean system backup. But what you probably want bien que is [creating a snapshot](http://www.gilham.org/Blog/Lists/Posts/Post.aspx?List=aab85845-88d2-4091-8088-a6bbce0a4304&ID=243). Il y a aussi a mount tool to get to le shadow copies programatically so you could actually move them off le volume as well. Il y a certains debate on how stable le VSS-based snapshot system really is et people have lost data. C'est a bit (ok, much more) involved than le approach used by Vmware as far as I can tell et is a bit more annoying to deal with.
Je pense il y a a service pack ou patch to le Windows Server 2008 Backup tool that makes it capable of [backing up the guests](http://blogs.msdn.com/taylorb/archive/2008/08/20/backing-up-hyper-v-virtual-machines-using-windows-server-backup.aspx) transparently by le way?
