Hi Alex,
We are using ceph mostly for shared filesystem with cephfs. As well as
some rbd images for docker volumes and a little s3 data. I have been
looking for a plan that can backup datas on rados level. But maybe I should
backup data seperately.
Thanks for the reply.

I would look into:
- RBD mirroring if using RBD
- Application level backups and remote replication (or Proxmox,
OpenStack etc, whatever you are using) to be aware of data consistency
- Export and import Ceph images
All depends on what are the applications, what are RTO and RPO
requirements, how much data, what distance, what is the network
bandwidth
