About database recovery using Storage Checkpoints
You can use Storage Checkpoints to implement efficient backup and recovery of
databases that have been laid out on VxFS file systems. A Storage Checkpoint
allows you to roll back an entire database, a tablespace, or a single database file
to the time that the Storage Checkpoint was taken. Rolling back to or restoring
from any Storage Checkpoint is generally very fast because only the changed data
blocks need to be restored.
Storage Checkpoints can also be mounted, allowing regular file system operations
to be performed or secondary databases to be started.
This chapter provides an introduction to using Storage Checkpoints for Storage
Rollback of an Oracle database. For full information on how to administer the
Storage Checkpoints feature for the database software that you are using:
See “About Storage Checkpoints” on page 267.
