Using Storage Checkpoints and Storage Rollback for
Backup and Restore
VERITAS Storage Foundation for Oracle RAC provides a Storage Checkpoint facility that is
similar to the snapshot file system mechanism. However, a Storage Checkpoint persists
after a system restart. A Storage Checkpoint creates an exact image of a database instantly
and provides a consistent image of the database from the time the Storage Checkpoint is
created. The Storage Checkpoint image is managed and available only through the
Storage Foundation for Oracle RAC command line interface (CLI). VERITAS NetBackup
also makes use of Storage Checkpoints to provide a very efficient Oracle backup
mechanism.
Note For more information on creating Storage Checkpoints with the CLI, see“Creating
Storage Checkpoints Using sfrac_ckptcreate” on page 144.
