Version Checkpoint

In a DB2 UDB EEE or ESE Data Partitioning Feature (DPF) environment, a Version Checkpoint is a set of checkpoints that spans multiple partitions. A Version Checkpoint contains one Storage Checkpoint per partition. A Storage Checkpoint is an efficient snapshot technology for creating a point-in-time image of a currently mounted VxFS file system. A Storage Checkpoint presents a consistent, point-in-time view of the file system by identifying and maintaining modified file system blocks.
