An excerpt from the official student guide "D108654GC10 - Oracle Database 19c: Multitenant Architecture", p220: "Database-level copy of a PDB. No storage-level snapshot is involved. Either a full copy of the source PDB or a sparse copy of the PDB."

A "PDB snapshot" is a point-in-time copy of a PDB. The source PDB can be open read-only or read/write while the snapshot is created. A clone from a PDB snapshot is a full, standalone PDB. A "snapshot copy PDB" is based on a copy of the underlying storage system. Snapshot copy PDBs reduce the amount of storage required for testing purposes and reduce creation time significantly.
