btrfs-restore:tldr:fb98b
The given command is used to restore data from a Btrfs filesystem using the "btrfs restore" command with specific options.
Here is a breakdown of each part of the command:
-
sudo: This command is used in Linux systems to execute a given command with root or superuser privileges. It allows the user to perform administrative actions.
-
btrfs restore: This is the main command that is being executed. It is used to restore data from a Btrfs filesystem.
-
--metadata: This option tells btrfs restore to restore metadata information. Metadata includes file attributes, permissions, and other information about files and directories.
-
--xattr: This option tells btrfs restore to restore extended attributes (xattr) of files. Extended attributes are additional metadata that can be associated with files and directories.
-
--symlinks: This option tells btrfs restore to restore symbolic links. Symbolic links are special files that point to another file or directory.
-
--overwrite: This option tells btrfs restore to overwrite existing files or directories in the target directory if they have the same names as the files being restored.
-
${path-to-btrfs_device}: This is the path to the Btrfs device or partition that contains the data to be restored. It should be replaced with the actual path to the Btrfs device.
-
${path-to-target_directory}: This is the path to the directory where the restored data will be stored. It should be replaced with the actual path to the target directory.
By combining all these options and variables, the command will restore the specified Btrfs filesystem's data, including metadata, extended attributes, and symbolic links, to the target directory, overwriting any existing files with the same names.
