Live backup of KVM virtual machines

This script will let you make backups of live VMs running on KVM, using libvirt.

The backup job will suspend the VM for the time it takes to copy the RAM to disk.

I've made some minor adjustments.

Edit 22/8/2021: I have updated MEmu and it seems like it reinstalls the apps and re-enables the services. Repeat steps 5, 7, 8, and 9 if you update MEmu.

Debloating MEmu

In my experience, Nox can be quite slow and choppy, and looks like I'm not the only person with this problem. A lot of people say that MEmu performs better than Nox, and I could agree with that. I have no chopping issues with it so far. But like Nox, there are kinda shady stuff going on.

The Windows version of OpenSSH client doesn't include a ssh-copy-id command. I don't know why. If it does one day, then this can be ignored.

NOTE If you have Windows Subsystem for Linux (WSL) installed, you can use the linux version of ssh-copy-id instead. Go to the description at the end of this document.

Download the file ssh-copy-id.cmd to your Windows PC, or copy and paste its contents.
Run the script passing your linux ssh information (for example ssh-copy-id.cmd [email protected]). This should work with any Linux platform. Alternatively, if you have experience, you can use the powershell version. ssh-copy-id.ps1. Run the script as powershell .\ssh-copy-id.ps1 [email protected].
Run the command for each linux account you connect with. You will be prompted for your Linux host password. If you have more than 1 account on any machine, you must do this for each account.

The file name and location of the script is not important but the filename extension must be .cmd

	Begin by enclosing all thoughts within <thinking> tags, exploring multiple angles and approaches.
	Break down the solution into clear steps within <step> tags. Start with a 20-step budget, requesting more for complex problems if needed.
	Use <count> tags after each step to show the remaining budget. Stop when reaching 0.
	Continuously adjust your reasoning based on intermediate results and reflections, adapting your strategy as you progress.
	Regularly evaluate progress using <reflection> tags. Be critical and honest about your reasoning process.
	Assign a quality score between 0.0 and 1.0 using <reward> tags after each reflection. Use this to guide your approach:

	0.8+: Continue current approach
	0.5-0.7: Consider minor adjustments
	Below 0.5: Seriously consider backtracking and trying a different approach
