+=== Backup of a FULL Linux installation ===

+  * used later for //restoring// the full installation
+  * used for //relocating// the full installation from ''C:\'' to another disk
+Detailed steps:
+  * 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 --verbose

+  NAME      STATE           VERSION
+* Ubuntu    Stopped         2</code>
+  * Export the specified Linux installation to a //tar// file:
+    * You should export to a directory or external disk where you have //enough// space\\ e.g. The tar file for a [[other:win10wsl#base_installation|newly installed and updated]] //Ubuntu 20.04.5 LTS// is ~1.G Gb
+    * You should use a detailed enough file name for the tar file\\ e.g. WSL_<Linux_Distribution>_<Distribution_Version>_<User>_<Date>.tar
+    * Example: ''wsl --export Ubuntu C:\Scratch\<your_login>\WSL\WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar''
