Example to replicate a BTRFS subvolume with an active sending side

The sending side "pushes" the BTRFS snapshot to the receiving side. The sender needs password-less SSH access to the receiver.

First, start the receiving side:

sudo btrfs-receive-chunks-passive \
  /target-snapshot-path/20230213T1809_u/

Then, start the sending side:

sudo btrfs-send-chunks-active \
  /source-snapshot-path/20230213T1809_u/ \
  ssh-hostname-of-receiving-side \
  /target-snapshot-path/20230213T1809_u/

See test16().
