Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)
A Storage Checkpoint of the primary fileset initially contains only pointers to the
existing data blocks in the primary fileset, and does not contain any allocated
data blocks of its own.
Figure 19-1 shows the file system /database and its Storage Checkpoint.
The Storage Checkpoint is logically identical to the primary fileset when the
Storage Checkpoint is created, but it does not contain any actual data blocks.
