Hello, I used btrfs some time to do incremental backups of large (200GB) VM images, which worked fine using snapshots and rsync (with --inplace to preserve COW). The only problem with this solution is that it takes extremely long due to rsync's performance on large files. For this reason, I can't await the btrfs send/receive feature. The latest discussion regarding send/receive that I know about is this one: http://thread.gmane.org/gmane.comp.file-systems.btrfs/12318/focus=12340 So my question is, especially to Jan Schmidt, are there any news on this feature? If there is no progress yet, would it be possible to create send/receive like features entirely in userspace at the moment, without touching too much kernel code? I remember that I've read a discussion some time ago about missing data for directory changes when using find-new. The discussion did not mention if this is a problem of the find-new command or a problem of the currently offered apis to the userspace? Is this still the case (or was it ever?) and are there any other pitfalls that I may come across while implementing a send/receive like tool in userspace. I'm asking because I'm not that experienced in kernel programming to actually add features on the kernel side.
