Ceph Snapshots for Fun and Profit

Ceph includes snapshot technology in most of its projects: the base RADOS layer, RBD block devices, and CephFS filesystem. This talk will briefly overview how snapshots are implemented in order to discuss their implications, before moving on to example use cases for operators. Learn how to use snapshots for backup and rollback-ability within RBD and CephFS, the benefits they bring over other mechanisms, how to use the new snapshot trim config options, and most importantly: how much they cost in capacity and IOPS!
