[ceph-users] Point-in-Time Recovery

Hello List, when reading: https://docs.ceph.com/docs/master/rbd/rbd-mirroring/ it says: (...)Journal-based: This mode uses the RBD journaling image feature to ensure point-in-time, crash-consistent replication between clusters(...) Does this mean, that mean, that we have some kind of transaction logs where we will be able to "walk to" a specific time to restore a specific state?
