As far as I know , rbd journal can be used to record all the rbd mutations to journal which is stored in rados objects in the same ceph cluster Is it has interface to push rbd journal to another storage device or another ceph cluster ? Or is is has dev plan? Or anyone has other good way to do backup ? Thanks very much!
