btrfs subvolume command [OPTIONS] [path]

btrfs subvolume manages btrfs subvolumes and snapshots. Subvolumes are separately mountable filesystem trees that can have independent snapshot and quota policies. Snapshots are point-in-time copies that initially share all data with their source.

create

Create a new empty subvolume

List all subvolumes in the filesystem

Delete a subvolume or snapshot

Create a snapshot of an existing subvolume

Deleting a subvolume does not immediately free space; asynchronous cleanup runs in the background. Snapshots are not recursive - nested subvolumes must be snapshotted separately.

btrfs subvolume is part of the btrfs-progs package for managing btrfs filesystems on Linux.
