- | There are several types of WSL related directories that you may want to back up: | ||
- | * <wrap hi>Your Linux //home// directory</wrap> (''/home/<your_login>''), or some specific sub-directories of the //Ubuntu// running in WSL (sub-directories of ''/''): all these files are located in a [[other:win10wsl#location_of_the_files|hidden sub-directory of you Windows directory]], and the best way to save them is probably to **create a tar file from Linux**, and put this tar file in a specific Windows //WSL backup folder// (we will use below the directory ''/mnt/c/Scratch/<your_login>'' or ''c:\Scratch\<your_login>'') | + | ==== Creating a backup ==== |
+ | |||
+ | === Backup of a FULL Linux installation === | ||
+ | |||
+ | You can use ''wsl'' to [[https://docs.microsoft.com/en-us/windows/wsl/faq#how-can-i-back-up-my-wsl-distributions--or-move-them-from-one-drive-to-another-|save a full Linux installation]] to a //tar// file, that can be: | ||
+ | * used later for //restoring// the full installation | ||
+ | * used for //relocating// the full installation from ''C:\'' to another disk | ||
+ | |||
+ | Detailed [[https://docs.microsoft.com/en-us/windows/wsl/basic-commands#export-a-distribution-to-a-tar-file|--export]] example: | ||
+ | * Determine the name of the current Linux installation(s) used in WSL | ||
+ | * <code>> wsl --list --verbose | ||
+ | NAME STATE VERSION | ||
+ | * Ubuntu Running 2</code> | ||
+ | * [[other:win10wsl#rebooting_wsl|Stop WSL+Linux]] | ||
+ | * <code>> wsl --shutdown | ||
+ | |||
+ | > wsl -l -v | ||
+ | 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 ~1.4 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%%'' | ||
+ | |||
+ | * If you are not going to use the backup tar file right away, you can optionally compress it in order to save some space | ||
+ | * <code>Add compression example here</code> | ||
+ | |||
+ | === Backup of specific directories === | ||
+ | |||
+ | You can also just create backups of specific directories: | ||
+ | |||
+ | * Your Linux //home// directory (''/home/<your_login>/''), or some specific sub-directories of the //Ubuntu// running in WSL (sub-directories of ''/''): the best way to save them is probably to **create a //tar// file from Linux**, and put this //tar// file in a specific Windows //WSL backup folder// (we will use below the directory ''/mnt/c/Scratch/<your_login>'' or ''c:\Scratch\<your_login>'') | ||

+ | |||
+ | This process is called //unregistering// (based on [[https://docs.microsoft.com/en-us/windows/wsl/basic-commands#unregister-or-uninstall-a-linux-distribution|Unregister or uninstall a Linux distribution]]) | ||
+ | |||

+ | === Removing WSL === | ||
+ | |||
+ | ''wsl'' is a part of the Windows system and probably can't be removed. | ||
+ | |||
+ | Anyway, when all existing Linux distributions are uninstalled, there should not be any big ''.vhdx'' files remaining (i.e. //no extra disk space used//), and there will not be any Linux processes running (i.e. //no extra CPU used//). | ||
- | * Make a backup of whatever you had in your Ubuntu home directory, and all the files and settings that are not in the ''/mnt'' directories | ||
- | * Find how to unregister Ubuntu on the [[https://docs.microsoft.com/en-us/windows/wsl/wsl-config|Manage and configure Windows Subsystem for Linux]] page | ||
