btrfs-restore:tldr:f5170
The command sudo btrfs restore --dry-run ${path-to-btrfs_device} ${path-to-target_directory}
is used to preview the restoration of data from a Btrfs filesystem.
Here is a breakdown of the command:
-
sudo
: This is a command used in Linux and Unix-like operating systems to execute a command with administrative privileges. It allows the user to run the subsequent command as a superuser or root. -
btrfs
: This is the command used to interact with the Btrfs filesystem. Btrfs is a modern copy-on-write file system for Linux. -
restore
: This is an action performed with thebtrfs
command to restore data from a Btrfs snapshot or backup. -
--dry-run
: This is an optional flag used with therestore
action. It performs a dry run, meaning it simulates the restore operation without actually making any changes to the filesystem. It is useful for previewing what would be restored before actually performing the restoration. -
${path-to-btrfs_device}
: This is the path to the Btrfs device or partition from which the data will be restored. It specifies the source of the restoration process. -
${path-to-target_directory}
: This is the path to the directory where the restored data will be placed. It indicates the destination where the restored data will be stored.
Note: In the actual command, the ${path-to-btrfs_device}
and ${path-to-target_directory}
should be replaced with the appropriate paths specific to your system.
