[kwlug-disc] question -- how to backup BTRFS to another BTRFS?

[B.S.]

As of today, that link is now also within 

https://btrfs.wiki.kernel.org/index.php/UseCases#How_can_I_use_btrfs_for_backups.2Ftime-machine.3F

It mentions other options as well, if useful:

Snapper
btrfs-time-machine
UrBackup
rsyncbtrfs

And some further proposed options.
