Try --postfix servername
it'll add the destination server in the snapshot rotation and the
lockfile.

Otherwise, you can just trivially modify the script to take --lock as an
argument, or you can even 
ln -s btrfs-subvolume-backup btrfs-subvolume-backupserver2
and the script will automatically make a /var/run/btrfs-subvolume-backupserver2
as a lockfile.

Hope this helps.
