Presumably your workload is deleting the previous backup before creating a new one? The most similar sounding bug is http://tracker.ceph.com/issues/24533, where the deletion path could get stuck. You can check your MDS logs for errors to see if it's the same. You can also look at the MDS performance counters (`ceph daemon mds.<id> perf dump`) and show us the "num_strays" fields and the purge_queue section.
