Make a complete Backup of a Hyper-V host with all VMs.....possible ?

Thread needs solution

Hey there,
currently I am waiting for Acronis fixing some bugs in ACP15 UD3.

In the meanwhile I rethought out baclkup strategy and came to the conclusion, that it would ease a bare metal recovery if I was able to do a full backup of my Hyper-V host.

But.....how?

I did tests on my current V12.5 system and I am not sure if it´s possible.

My system:

a) the physical server
Physical Server with a total of 7 HDD (windows count them from Disk 0 to Disk 6)
There I want only to backup Disk 3 and 4.
Disk 3 contains the system partition and the system itself, Disk 4 is the location where the files of the virtual machines are stored.
I use Hyper-V as hypervisor.

b) VM1
The files of this VM are stored on Disk 4 of the physical server.
This VM has 2 disks, I want to backup all of them.

c) VM2
The files of this VM are stored on Disk 4 of the physical server.
This VM has 2 disks, I want to backup all of them.

d) VM3
The files of this VM are stored on Disk 4 of the physical server.
This VM has 4 disks, I want to backup all of them.

Hmmm it seems simple....but if I try to setup the plan I am somehow confused.

In my eyes it is a Disk/Volume backup right ? So I select the in the "What to backup".

Then I select the device by selecting the Host in the "Hyper-V --> Hosts and Clusters" section (see screenshot).

So far so good....but now I must use policy rules to specify what tho backup.
First thing I recognized: Acronis starts counting from 1, whereas Windows starts from 0.
So no problem add 1 to the Windows Disk number but....

I must specify
- Disk 4 and 5 for the physical
- Disk 1 and 2 for VM1 and VM2
- Disk 1, 2, 3 and 4 for VM3.....

So the backup inludes also Disk 1, 2 and 3 for my physical machine, but that´s not what I want.....

Any idea how I can do a backup to speed up bare metal recovery?

Would it be an option to specify [BOOT+SYSTEM] and the drive names?

Or specify "entire machine" and then exclude the non wanted drive letters ?

Any hints are welcome.

Push...

Is my question that strange that no one has any hint for me?

Or is that a usecase that is not needed by anyone?

Good morning Sven,

we ensure a bare metal image of our Hyper-V Hosts including VM config etc. with a backup job of the host excluding *.vhdx files. This backups all system files, partition information, configs, license information etc. but no data ...

Selecting the Host as source without excluding anything should backup everything including os, configuration and data (VMs) from all physical drives.

Hey Erik,

if you exclude the vhdx files, how can you then restore the VMs if you need a bare metal restore ?
After you restore the ipper mentioned backip the VHDX files are missing and so the VMs cannot start.

How do you then restore the VMs in non existing VHDX ?
I have the experience, that if you create the necessary VHDX in that moment, the IDs are different and that lead to problems.

 

Selecting the Host as source without excluding anything should backup everything including os, configuration and data (VMs) from all physical drives.

That is clear but I have to exclude some of the physical volumes on the Hyper-V host.
The reason for this exclusion is that these volumes are used for data transfer, manual backups and one of the volumes is a 12TB RAID storage that is used as one of the backup locations to reduce the RTO.

Hello Sven.

We recommend creating two separate tasks for backing up a host and another task to back up VMs and set them up to run at different times. This is to separate creating snapshots.

However, you can still select the host and VMs in one task:

Then I select the device by selecting the Host in the "Hyper-V --> Hosts and Clusters" section (see screenshot).

Here you selected a host. You should also navigate to Machines with Agents and select your VMs there.

Hello Matia,

well this would work if i want to do full backups.

In that moment, when I need exclusion, I need separate tasks....

 

Honestly spoken I am slightly disappointed, that such a normal task "backup the complete system with exclusions" is that hard to realize with Acronis.
Other products do this much better,...

 

For me that point is gone. I will create 2 tasks as I cannot spend more time on discussions why Acronis cannot do the job like other tools do.

Hello Sven.

It is not clear why you can't apply exclusions if created tasks as I described above.

 Maria,
Did you read my first post in that thread?
There I described what I want and what to exclude.

And this is currently not possible with one single task

Yes that is correct, that I can select there the machines.
But - and that is the important issue - how can I then define the necessary exclusions?

 

The only workaround is doing 2 tasks....

Hey Maria,
does that really work ?

So if I understand you correct I do a backup of the entire machine. And then exclude via file filters the drives on the host that I don´t want right?

In my case I would exclude F, G, H I and T.

That would exclude the not wanted drives on the Host.

 

How are the virtual machines backed up?
On the one hand I have the vhdx files on the host and the files and drives inside the VMs.

So what is in the end in the backup? Only the vhdx (so that the VMs have the configured files for their drives), only the file backups from inside the VM or both?
 

Thanks in advance

Sven
