+============================================================
+ cephfs-mirror -- Ceph daemon for mirroring CephFS snapshots
+============================================================
+
+.. program:: cephfs-mirror
+
+Synopsis
+========
+
+| **cephfs-mirror**
+
+
+Description
+===========
+
+:program:`cephfs-mirror` is a daemon for asynchronous mirroring of Ceph
+Filesystem snapshots among Ceph clusters.
+
+It connects to remote clusters via libcephfs, relying on default search
+paths to find ceph.conf files, i.e. ``/etc/ceph/$cluster.conf`` where
+``$cluster`` is the human-friendly name of the cluster.
+
+
+Options
+=======
+
+.. option:: --mon-host monaddress[:port]
+
+   Connect to specified monitor (instead of looking through
+   ``ceph.conf``).
+
+.. option:: --keyring=<path-to-keyring>
+
+   Provide path to keyring; useful when it's absent in standard locations.
+
+.. option:: --log-file=<logfile>
+
+   file to log debug output
+
+.. option:: --debug-cephfs-mirror=<log-level>/<memory-level>
+
+   set cephfs-mirror debug level
+
+.. option:: -c ceph.conf, --conf=ceph.conf
+
+   Use ``ceph.conf`` configuration file instead of the default
+   ``/etc/ceph/ceph.conf`` to determine monitor addresses during startup.
+
+.. option:: -i ID, --id ID
+
+   Set the ID portion of name for cephfs-mirror
+
+.. option:: -n TYPE.ID, --name TYPE.ID
+
+   Set the rados user name (eg. client.mirror)
+
+.. option:: --cluster NAME
+
+   Set the cluster name (default: ceph)
+
+.. option:: -d
+
+   Run in foreground, log to stderr
+
+.. option:: -f
+
+   Run in foreground, log to usual location
+
+
+Availability
+============
+
+:program:`cephfs-mirror` is part of Ceph, a massively scalable, open-source, distributed
+storage system. Please refer to the Ceph documentation at https://docs.ceph.com for
+more information.
