okay. I tested cinder backup to 2nd ceph cluster. 1. I created full backup 2. I created incremental backup
But on 2nd ceph cluster I see two full size backup (each 20G) Do anybody know why? rbd --cluster bak -p backups du warning: fast-diff map is not enabled for volume-46a306ae-2454-4425-a6f7-96d7c02acc95.backup.c6a0f070-abc1-4e6f-93c7-c60ef1bcf3e3. operation may be slow. warning: fast-diff map is not enabled for volume-46a306ae-2454-4425-a6f7-96d7c02acc95.backup.ec9a671f-9c12-4ce4-8772-3e2d74c62ca0. operation may be slow.
