Ceph snapshots rely on client cooperation in determining which operations apply to which snapshots, and appropriately flushing snapshotted data and metadata back to the OSD and MDS clusters. Because snapshots apply to subtrees of the file hierarchy and can be created at any time, there is a fair bit of bookkeeping required to make this work. Portions of the hierarchy that belong to the same set of snapshots are described by a single 'snap realm.' A 'snap context' describes the set of snapshots that exist for a given file or directory.
