Hyper-V: BDR Backup

Posted on 2014-08-07

Last Modified: 2014-11-12
I have a Windows 2012 R2 Server Std running the Hyper-V Role with 3 VMs.

I have a BDR to back up my servers.  I assume I backup my VMs to the BDR but What about the Host?  Do I backup the Host's Boot partition?  Can I and Should I place the VM configuration on the boot drive leaving the VHDX files on the second partition that I would not backup?  Is that even possible?

In the event I need a restore and the BDR can provide the .VHD file, what steps are needed to pull the VM back together?

What are the steps if the host needs a BMR to restore the host and the VMs?

Thanks.  Newbie.

I would create a separate array/LUN e.g. a D: drive and put all your VMs on the D: drive, leaving the C: drive for your OS.

Then you can use Windows Backup to backup your OS.

So, let the BDR backup the VM.  But don't let the BDR backup the HOST/OS?  Why not?

Do I have Windows Backup run regularly or is that a resource concern?

If I have to replace the Hardware on my Host,  How do I get the VM configurations/settings back?

Can BDR backup and restore the host? - Check your specifications.

How often do you want to backup your OS - how often are you changing the configuration?

Backup once a day, once a week?

Restore - Boot the Windows 2012 R2 DVDROM, Select Restore, and follow the wizard.....

Make sure you understand and practice this...

OR, do not bother with Host Backup, and Keep Good Documentation on How to build and configure you server...

Sry.  Let me ask my question in a clearer fashion:

If I have to rebuild my STANDALONE Hyper-V host, I would install the OS from scratch or restore that OS partition from an Image....... My VMs are on a BDR and they can provide a .VHD when I'm ready to restore.  

How o I get back the Settings / Metadata?  or Do I just recreate it?

Using Windows Backup there is no need to Install and OS from scratch, and then restore the OS parititon....

it's a complete waste of time re-installing an OS....

The Microsoft Backup and Restore way us.....

Microsoft Backup the Server OS to a Network File Share.....

BOOT the Server from the CDROM/DVDROM (the DVDROM you would install from!) but rather than  install you select Repair/Restore, select the Network File Share Backup and CLICK Restore....Wait, Reboot and your DONE!

Here is the process here....some videos I've created (there is no audio, but you can watch the process!)

If your BDR backup just copies the VHD, it's not really very complete......you should really have a copy of the VHD and Metadata/Settings for complete backup.

You could include those settings in your Windows Backup! (Host Backup!)
