- if your workload is virtualization, we recommend all flash. For non latency sensitive / slower iops you can use HDD witj SSD journal, you can also use SSD write cache to improve latency and iops iwith HDDs. Use NVMEss for journals to HDD ( ratio 1:12-16) or to SSD ( 1:4), using NVMEs for OSDs gives the same performance as SATA SSDs. Use enterprise grade SSD/NVME.
- We currently do not support backups but it is intended, we currently support replication among clusters. To support backups yourself you need to use Ceph directly to create snapshots and exporting images or snapshots differences, look at the rbd snap, rbd export and rbd export-diff commands, probably run in script or cron job.

Hi Team,
Can you please help me on commands to use ceph directly to create snapshots & exporting images or snapshots , rbd snap ,rbd export or script or cron jobs. In internet , We are not finding any useful blog about backup & restore .
Thank you in advance,
Abhishek

in ui when you deploy the first node and create a cluster, you can bond interfaces to the management interface. Since you are connected while doing this, make sure you choose a bond mode that does not require reconfiguration by the switch

Just by the types of questions you are asking. I am not in any way trying to sound condescending, but many of your questions are very much intro questions. I would definitely just consider official support thats all!
