The upcoming release of Samba 4.2 will offer integration with Snapper, providing the ability to expose snapshots to remote Windows clients using the previous versions feature built into Windows Explorer, as demonstrated in the following video:
... [share] vfs objects = snapper path = /mnt/btrfs_fs
The share path must correspond to a Btrfs subvolume, and have an associated Snapper configuration. Additionally, Snapper must be configured to grant users snapshot access - see the vfs_snapper man page for more details.
