+ | ==== 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 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 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.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_20.04.4_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> | ||
+ | |||
+ | === Other types of backup === | ||
+ | |||
+ | |||
+ | ==== Restoring or relocating a Linux installation ==== | ||
+ | |||
+ | When we have a backup in a tar file, we can restore it to the default location (Check ?? FIXME), or specify where we want to restore it. This is a way of moving (relocating) an installation to another disk or partition than the default location ''C:\'' | ||
