| + | ==== 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>$ ls -lh /mnt/c/Scratch/<your_login>/WSL/WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar | ||
| + | 1.4G Aug 29 17:49 /mnt/c/Scratch/<your_login>/WSL/WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar | ||
