Windows 10: VM Servers are not backing up

I have to virtual machine servers that are having issues backing up. Below is some background to get in to how I came to the issue I am experiencing:We back them up to Datto, and after working with Datto support, they mention that the issue is with the virtual machines themselves. Based on the errors and logs that were given, they said to run a CHKDSK /F/R and see if that would fix the issues.When I did that about 2 weeks ago, it ended bricking the server, and we were able to run a VM from a local Datto device. While the VM was running from the Datto device, it was backing up with no issues. O

VSS problems backing up windows 2012 R2 server VM in hyper-v server

I have a single Hyper-V 2012 R2 server host with 2 VMs running windows 2012 R2 server with the latest updates.

The VMs are backed up using Altaro VMBACKUP which runs on the host.

The first VM is a DC which is backed up successfully.

The second VM OS is Windows 2012 R2 with Exchange Server 2013 onpremise.

This VM has been backing up for years without any problem and since 2 months ago the backup has been failing.

The Altaro VMBACKUP shows the following error:

There was a problem while rolling back the latest failed backup for this VM to the last consistent state. (Error code 'ROLLBACK_306')
The rollback will be attempted again automatically before any subsequent backups or restores on this VM until it is successful, so the health of the backup data should not be affected.
Additional information is available:
There was a problem while rolling back the latest failed backup for this VM to the last consistent state. (Error code 'ROLLBACK_016')
The rollback will be attempted again automatically before any subsequent backups or restores on this VM until it is successful, so the health of the backup data should not be affected.

 

Licensing Legacy Windows Products on a VM Server

Hello,

Can someone from Microsoft confirm what licenses would be needed to fit the following use case:

• Need to license legacy as well as current Windows products (XP, 7, 10)
  
• The VMs will only have one user account that gets used, but would be utilized by multiple developers in our org
  
• The VMs would be hosted on a physical server and would be accessed through RDP
  

 

Can a Physical Server and a VM Server coexist with the same license?

We have a client that has recently cloned their physical 2012 server, running Parallels, to a VM server. They want to use this VM server as fall back when and if that physical server goes down. This VM will only be turned once the physical server is down allowing remote users to log in. Can this be done? Our concern is with Windows licensing and what issues may arise with having both servers on at the same time if needed.

Can both coexist with the same license, or do we need to purchase a new license?
