[LINUX] Hot backup and restore of virtual machines in Hyper-V Server 2019
Introduction
I was wondering how to back up my home mackerel virtual machine. You can easily do this by using the following method.
environment
- Samsung Chromebox Series 3 --8gb memory --System Storage: Install Hyper-V Server 2019 on USB SSD 120GB --Backup storage: USB memory is inserted [^ 7]
Backup of the main unit
There seems to be no choice but to clone it regularly with Filezilla. I thought, but it seems that it can be done in the same way.
wbadmin ** With this method, you can only restore to the exact same hard disk that you backed up. It cannot be restored to another because the storage is corrupted. ** ** At least I have a backup. If you want to save to a remote network disk Save your logon credentials with cmdkey /add 192.168.1.xx / user: username / pass: password.

Otherwise, I tried using EaseUS Todo Backup Server with Microsoft Hyper-V Server 2016.
Creating a virtual machine
Drop the iso
Download it like wget. [^ 3]
Invoke-WebRequest -Uri http://releases.ubuntu.com/18.04/ubuntu-18.04.3-live-server-amd64.iso -OutFile C:\dl\ubuntu-18.04.3-live-server-amd64.iso
Create
Create a network etc. as shown in the image below (not sure if it is essential)
OS installation
Install it. I set / boot to ext4 and the others to xfs. Here, the username is hani and the password is passwd2020.
Also, install docker [^ 2] and put the nginx container.
sudo su
apt update
apt install curl
curl -fsSL https://get.docker.com/ | sh
docker create -P --name nginx bitnami/nginx:latest
docker start nginx
installation of hyperv-daemon
For hot backup, the guest must have a daemon.
wget http://ftp.jp.debian.org/debian/pool/main/l/linux/hyperv-daemons_5.3.15-1_amd64.deb
dpkg -i hyperv-daemons_5.3.15-1_amd64.deb
reboot
Preparations are now complete. Leave it running.
backup
Find a virtual machine to back up
After logging in with Remote Desktop from Server Manager, view the VM list with cmd.exe. [^ 4]
wbadmin get virtualmachines
C:\Users\Administrator>wbadmin get virtualmachines

backup!
Execute cmd.exe as follows (f: is the SSD to be backed up, ubutest1 is the virtual server to be backed up)
wbadmin start backup -backupTarget:f: -hyperv:ubutest1
You can back up like this.
restore
Plug the USB storage into your PC.
View backup list
Check the backup contents. (I was backing up twice.)

Turn off the server (for experimentation)
Turn off the server. Because it's a restore test.
(With powershell)
Stop-VM ubutest1 -Force
Remove-VM ubutest1
restore!
I will try to restore it.

error-This feature is not available in a portable workstation environment.
I wonder what this is, it may be because I put os in Usb in this environment. [^ 5]
The cause may be a misidentification of the Windows To Go environment. (Omitted) I think this can be avoided by deleting the following registry value or setting the data to 0 and restarting Windows. Key: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control Name: PortableOperatingSystem
Change the above registry on the remote desktop to shutdown / r.
regedit
I set it to 0.
