| ==== Creating a backup of the Linux running in WSL ==== | ===== Advanced usage ===== |
| |
| 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 steps: |
| | * 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>'') |
| * <code bash>$ cd /home | * <code bash>$ cd /home |
| |
| 95K Feb 24 12:09 /mnt/c/Scratch/<your_login>/<your_login>_home_210224_1209.tgz</code> | 95K Feb 24 12:09 /mnt/c/Scratch/<your_login>/<your_login>_home_210224_1209.tgz</code> |
| |
| * <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]]) | * Regular Windows folders 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]]) |
| | * WARNING: there should not be performance issues using ''tar'' (from Linux) to make a backup of Windows files with WSL 1, but **WSL 2 is significantly slower than WSL 1 to access Windows files** ([[https://docs.microsoft.com/en-us/windows/wsl/compare-versions#exceptions-for-using-wsl-1-rather-than-wsl-2|Exceptions for using WSL 1 rather than WSL 2]]) |
| |
| * <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 | |
| Distributions du sous-système Windows pour Linux : | |
| Ubuntu (par défaut) | |

| * Export the current Linux to a //tar// file: | |

| * 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> | |
