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 the btrfs command to restore data from a Btrfs snapshot or backup.

• --dry-run: This is an optional flag used with the restore 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.
