As a list regular and btrfs user myself, but not a dev... No idea about zfs and my own btrfs use-case doesn't use btrfs send/ receive either, so this is primarily from previous list posts, with a quick look at the (v4.4.1) btrfs-send manpage as well... Recursive send isn't yet supported, only one at a time. Based on a previous comment from someone who apparently looked at the code (but isn't a btrfs dev either), there's possibly some code for -r (recursive) already in the repo (or maybe it's simply a comment reserving the -r option?), but it doesn't work yet. However, it shouldn't be horribly difficult to hack up scripts that automate the otherwise manual recursive-send/receive for you, as I'd very likely do myself if I needed that functionality. =:^) -- Duncan - List replies preferred.
