Hi all,
We have Hyper V Core running a single VM (Server Essentials 2016). If we try and do a checkpoint, the VM dies and is left in a stopped/critical state. We then have to shutdown the VM and delete the created checkpoint. We're trying to use Altaro VM Backup (as recommended by someone who's amazing with Essentials, a'hem Mariëtte) but this relies on being able to complete the checkpoint without it killing the VM. Does anyone have any idea what could be causing this? I've tried pointing the checkpoints to an external disk (just in case it was storage related) but this didn't make any difference at all.
Wanting to use Altaro VM Backup to backup the existing VM but just can't get this working. Help me OB1 Mariëtte - you're my only hope :)
Regards
Steve
Hey Steve :) Hope you are fine to. Happy New Year :)
Checkpoints are saved to a specific directory, you can check this through the GUI but also with Powershell:
Get-VM -Name VMName | Fl *checkpoint*
Where are the checkpoints stored? Maybe a solution is to change the location to some other drive?
Hi Mariëtte,
Happy new year :)
I've pointed the checkpoints to an external drive.
I've got a post on SpiceWorks with more info: https://community.spiceworks.com/topic/2501835-cannot-create-checkpoints-hyper-v?page=1#entry-10477839
I think the issue is the host disk hasn't got enough space on it? Not quite sure how to get around it though?
Good catch! Well, the way to get this fixed is to get more disk space. But a better solution is to migrate to Windows Server 2022 on a new host. You need to make a plan for that and tell management to give you their credit card and start spending money.
Ha! You know the score, they won't put their hands in their pocket for such "trivial" things... ¯\_(ツ)_/¯
We only have the one VM as you know but it has 2 virtual disks assigned to it (one for the OS <C> and another for the data shares <D>).
Is it not possible to disconnect the D (data) drive, run a check point (and thus VMBackup) on the OS, then reconnect the D drive?
Do you envision any issues doing this? Is this even possible?
In a nutshell we want to upgrade Essentials 2016 to Standard 2016 so we can get around the 25 user limit.
I've tested the process on a test server (where the checkpoints worked fine) and it was great. We actually brought Altaro VMBackup specifically for this purpose so I can backup the current Essentials 2016, upgrade to Standard 2016, back that up (just in case) and carry on.
