Hyper-V Backup

Windows 2012 R2 Hyper-V is hosting 4 vm's. Should the hyper-v host be backed up or only the vm's? I'm looking for complete recovery. Network configuration to be backed up?

How long does it take to you to create a Hyper-V Host ?

I would recommend for complete recovery, you backup the Hyper-V host, excluding the VMs, and pagefile.

Windows Backup can do this, to a network share, and using the 2012 Media, you can restore your host.

I also recommend backing up the host. Although as a minor difference (perhaps only in terminology), I recommend backing up the VM configuration files and exclude *only* the VHD files. The config files ensure you keep the same settings, right down to the virtual network adapters and their generated MAC addresses, which can make bringing back a guest much easier.

The problem is restoring the host from scratch requires time and effort(patches and tweaks),so yeah,I would back it up for DR .

Why should I exclude the vhd files? those are the guests os. I need them. Also where are the vm config files stored so I can back them up?

Create two jobs

A. A Host Job (exclude VHDs)
B. A VM Job (include VHDs and Metadata, which is stored in a folder adjacent to the VHD)

Use it to Backup the VMs, this is what it's designed to do.

and use WIndows Backup to backup the Host.

This is the most efficient and quickest method. As Altaro will use block mode to backup the VMs.

The only way to remove the page file from backup is deselect bare metal recovery in Windows backup. Should this be done?
As well, if i select to backup Host Component, do i still need to select the vm configuration file folder?

pgm554Commented:
What you could do for a page file is create a small NTFS partition(must be NTFS!)and set it as your page file.

That way your bare metal restore should be a no brainer.

Altaro will backup the entire VM, so no need to worry about the metadata.

find which file/folder is the reparse point.

You will need to find which file. Look in the backup logs
