Btrfs devel - Jan 2014 - Can you keep reflink relationship during a copy/backup to another filesystem?

So I used to use hardlinks to do historical backups of the same filesystem
but I know it's preferable to use refllink with btrfs to avoid having too
many hardlinks.

But if I need to backup this filesystem to another one some other way than
btrfs send/receive (let's say cp -a, tar, or rsync), is it correct to say
that reflink relationships will be lost and my data will take more space?

That is unless the target filesytem can do deduplication like btrs now can?
(I haven't tried it yet, but it's about time that I do)

Thanks,
Marc
