[ceph-users] How to synchronize pools with the same name in multiple clusters to multiple pools in one cluster

We have ceph clusters in multiple regions to provide rbd services. We are currently preparing a remote backup plan, which is to synchronize pools with the same name in each region to different pools in one cluster. For example: Cluster A Pool synchronized to backup cluster poolA Cluster B Pool synchronized to backup cluster poolB I read the rbd-mirror documentation, but I don't understand how to start synchronization using bootstrap mode.
