Description

The guide currently describes how to backup content, but for some use-cases it may be useful to also describe how to backup (and restore) the Docker Desktop VM as a whole;

• Describe the location of the VM disk on each platform
• Describe steps to back-up the VM (on macOS this can also mention "include VM in time machine backups")
• Backing up the VM may require docker desktop to be stopped while making the backup
• On Windows with WSL 2, this can mention how to backup the drive for the distribution;

Backup WSL Linux distributions:
		If you are using any WSL2 linux distributions, back them up and restore later following the instructions here:
			https://learn.microsoft.com/en-us/windows/wsl/faq#how-can-i-back-up-my-wsl-distributions-
	
Backup Docker containers/images:
		Backup docker_data.vhdx file. Default location is %LOCALAPPDATA%/Docker/wsl/disk/docker_data.vhdx. Later restore it to the same location if needed.
