I use rsync to copy data (~10TB) to backup storage.

To speed things up I use the ceph.dir.rctime extended attribute to instantly ignore sub-trees that haven't changed without iterating through their contents. I have to maintain the ceph.dir.rctime value between backups: I just keep it in a file per top-level directory on the target storage. This sounds interesting. Can you give some advice how to set this up with rsync?
