Linux(Ubuntu), Export & Import
Let's manage Ubuntu history, just like snapshots in VirtualBox.
In WSL (Windows Subsystem for Linux), Ubuntu is managed and stored in a virtual disk file called ext4.vhdx. Since I plan to conduct various tests, there will be times when I need to revert to a previous version. VirtualBox provides a snapshot feature, but unfortunately, WSL does not.Therefore, I will use WSL’s export and import functions to manage system versions.
Export & Import Ubuntu
Follow the commands below to proceed. Be cautious: if you use wsl --unregister Ubuntu, the ext4.vhdx file will also be deleted!!! Use it carefully.
wsl --export Ubuntu "D:\01.WSL\ubuntu-1-install_wsl.tar"
wsl --unregister Ubuntu
wsl --import Ubuntu "D:\01.WSL" "D:\01.WSL\ubuntu-1-install_wsl.tar"
ubuntu config --default-user jaoneol
