Hi, let's assume a huge ceph clusters, with 300TB full of datas (rgw, rbd and the future cephfs) How will you manage backups of this cluster? Will snapshot be enough? For example, one snapshot per day should be allow me to revert or restore a single file from the previous day.
What's your retention policy? For example a financial institution may be legally required to keep transaction information for 10 years. Or 25. Can you afford enough disk for 3652 snapshots of 300TB?
