Description
Introduce a rsync like tool (cephfs-sync) for mirroring scheduled and temp cephfs snapshots to sync targets. sync targets could be ceph filesystem on a remote site or even a traditional filesystem. We may want to sync to remote ceph filesystem initially.
We would start with scanning the filesystem based on rctime and feed the file list to rsync. Later, implement (or provide an option) to switch using various sync mechanisms that are much more efficient (such as identifying renames and propagating that to the remote target rather than a copy and delete).
