Hi Tobias, I don't think there is a way to accomplish that within Ceph. The existing RBD snapshot scheduling functionality is limited to mirror snapshots. I have seen a few referenced on this mailing list -- typically they are under a few dozen lines of Bash so people tend to write them from scratch tailored specifically to their environment (OpenStack, etc).
