@All, I just read about a "send/receive feature in Kernel-3.6 for btrfs which can be used by backup solutions to determine the difference between snapshots" http://www.h-online.com/open/news/item/First-release-candidate-of-Linux-kernel-version-3-6-1659576.html http://lwn.net/Articles/506244/ This is a very efficient interface for backup tools, especially for large Cluster File Systems! Can we put it on the feature list for Ceph-FS ?
