| - | 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:\'' | + | When we have the tar file of a [[other:win10wsl#creating_a_backup|FULL backup]], we can use [[https://docs.microsoft.com/en-us/windows/wsl/basic-commands#import-a-new-distribution|--import]] to install or restore it to a specific location. |
| + | |||
| + | Note: | ||
| + | * This is currently the only way of moving (relocating) a Linux installation to another disk than the default ''C:\'' location | ||
| + | * Importing will mostly put the ''ext4.vhdx'' file in the specified target location! | ||
| + | * You need [[other:win10wsl#disk_usage|enough disk space]] in the new disk location, knowing that the size of the ''vhdx'' file will start growing (as needed) as soon as you use your installation | ||
| + | * This is an indirect way of reclaiming the unused space of a Linux installation, i.e the size of the ''ext4.vhdx'' file after importing can be smaller than the size of the originally exported ''ext4.vhdx'' file. | ||
| + | |||
| + | Detailed [[https://docs.microsoft.com/en-us/windows/wsl/basic-commands#import-a-new-distribution|--import]] example: | ||
| + | |||
| + | * We assume that we have an exported installation tar file available | ||
| + | * In this example, we use the compressed backup file created in [[other:win10wsl#backup_of_a_full_linux_installation|Backup of a FULL Linux installation]]\\ ''C:\Scratch\<your_login>\WSL\WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar.gz'' | ||
| + | * Create the directory where the Linux installation (mostly its ''ext4.vhdx'' file) will be restored | ||
| + | * Hint: use an explicit directory path and name using the name of the distribution that will be restored\\ e.g. ''D:\WSL_Distributions\Ubuntu_custom'' | ||
| + | * Import the distribution, giving it a name that does not appear in ''wsl -l -v'' | ||
| + | * <code>> wsl -l -v | ||
| + | NAME STATE VERSION | ||
| + | * Ubuntu Stopped 2 | ||
| + | |||
| + | > wsl --import Ubuntu_custom D:\WSL_Distributions\Ubuntu_custom C:\Scratch\<your_login>\WSL\WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar.gz | ||
| + | > wsl -l -v | ||
| + | NAME STATE VERSION | ||
| + | * Ubuntu Stopped 2 | ||
| + | Ubuntu_custom Stopped 2</code> | ||
| + | * After importing, there should be a new ''ext4.vhdx'' file in the previously empty ''D:\WSL_Distributions\Ubuntu_custom'' directory | ||
| + | * Start the imported ''Ubuntu_custom'' distribution | ||
| + | * Directly from the Windows Terminal pull-down menu | ||
| + | * Or from a PowerShell, using ''wsl --distribution Ubuntu_custom'' | ||
| + | * WARNING: even if the distribution we imported had an existing default ''stdu'' user, the //new// default user will be ''root'' ! | ||
