btrfs-subvolume: Create a read-write snapshot of an existing subvolume.
$ sudo btrfs subvolume snapshot ${path-to-source_subvolume} ${path-to-target}
try on your machine
This command is used to create a snapshot of a specific subvolume in a Btrfs file system.
Here's a breakdown of the command syntax:
sudo: This is a command used in Linux systems to execute a command with administrative (root) privileges.btrfs subvolume snapshot: This is the main command for creating a snapshot of a subvolume in the Btrfs file system.${path-to-source_subvolume}: This is the path to the source subvolume you want to create a snapshot of. The syntax${}is often used to represent a variable, so you need to replace${path-to-source_subvolume}with the actual path to the subvolume.${path-to-target}: This is the path where you want the snapshot to be created. Again, you need to replace${path-to-target}with the actual desired target location for the snapshot.
By running this command with the appropriate paths, you can create a copy (snapshot) of the specified subvolume in the Btrfs file system.
