Hm... I don't fully understand your response, but maybe my question was not clear.
My use case is this:
Running PVE + Ceph Cluster I want to store backups in a RBD.
Creating a RBD with PVE only allows me to select storage content Disk-Image and Container.
As a workaround I created a RBD manually and defined storage type "directory" pointing to mounted rbd on filesystem.

It normally doesnt serve any purpose to use the same disks for data and backup; its not a backup if taking our the primary takes it out too. That said, if you want to use ceph for you backup images use cephfs (https://pve.proxmox.com/pve-docs/chapter-pvesm.html#storage_cephfs)
I never said that I want to use the same storage for backup, Disk-Image and Container.
This makes no sense at all.
But I want to create a storage of type rbd to be used for backup.
This would create another rbd in a specific pool that is only used for backups.

rdb - rados block device
block devices are best for VM images and CT images.
take a look on cephfs, if you need a filesystem on top of ceph.

You would need to mount it separately and add a file system on top. As previously mentioned better look into CephFS.
