   * <wrap hi>Regular Windows folders</wrap> where you store data used by WSL: you can use ''tar'' in a Linux terminal, as above, or use any usual way of backing up Windows files (drag and drop, some specific [[other:win10apps#backup_software|backup software]])
-  * <wrap hi>The **full** Linux/Ubuntu installation</wrap> running in WSL (based on [[https://docs.microsoft.com/en-us/windows/wsl/faq#how-can-i-back-up-my-wsl-distros-or-move-them-from-one-drive-to-another|How can I back up my WSL distros?]]). The following steps will save the full installation in a tar file, that can be used later for restoring the full installation (//restoration// not tested yet)
-    * Open a **Windows terminal** (preferably a //PowerShell// if you need easy copy/paste)\\ The //Windows// terminal is where you will type the ''wsl'' commands shown below
-    * Determine the name of the current Linux installation used in WSL (and see if it is running, and using //WSL 1// or //WSL 2//)
-      * <code>> wsl --list --all

-        * 1.4 Gb
-      * <code> > wsl --export Ubuntu C:\Scratch\<your_login>\<your_login>_ubuntu-<ubuntu_version>-full_<some_date>.tar</code>
-    * You can optionally open a new terminal (this will start again WSL+Ubuntu) to get some information about the created file (size and number of saved files/directories), and compress it in order to save some disk space
-      * <code>$ cd /mnt/c/Scratch/<your_login>
