Hi Frantz The output of 'btrfs send' is in binary format. You can read more about what is contained in the data stream in Jonathan Corbet's posting at LWN here http://lwn.net/Articles/506244/ You'd normally do send/receive something like this: btrfs send /backup/start | btrfs receive /destination There are also some notes on the btrfs wiki here, by Alexander Block https://btrfs.wiki.kernel.org/index.php/Design_notes_on_Send/Receive however I believe these are a bit out of date now. You can look at the latest code for btrfs-progs here: http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-progs.git;a=summary you may in particular want to look at Alexander Block's patchset here: http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-progs.git;a=commit;h=f1c24cd80dfd037407cdee85181646adca6dd5bb -- Rory Campbell-Lange r...@campbell-lange.net -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
