A Storage Checkpoint is like an online backup of a database, including partitioned databases, that contains a point-in-time database image. Storage Checkpoints can later be used to restore the image of the entire database to any earlier state recorded by the Storage Checkpoints. You cannot recover a container or a tablespace. Storage Checkpoints are used in a DB2 UDB EE environment. DB2 UDB EEE (SMP only) supports data partitioning across clusters of massively parallel computers.
