since a previous Storage Checkpoint was taken. Storage Checkpoints have the

following important features:

■ Storage Checkpoints persist across system reboots and crashes.

■ A Storage Checkpoint can preserve not only file system metadata and the

directory hierarchy of the file system, but also user data as it existed when the

Storage Checkpoint was taken.

■ After creating a Storage Checkpoint of a mounted file system, you can continue

to create, remove, and update files on the file system without affecting the

image of the Storage Checkpoint.

■ Unlike file system snapshots, Storage Checkpoints are writable.

■ To minimize disk space usage, Storage Checkpoints use free space in the file

system.

Storage Checkpoints and the Storage Rollback feature of Veritas Storage

Foundation for Databases enable rapid recovery of databases from logical errors

such as database corruption, missing files and dropped table spaces. You can

mount successive Storage Checkpoints of a database to locate the error, and then

roll back the database to a Storage Checkpoint before the problem occurred.

See “About database recovery” on page 79.

See the Veritas Storage Foundation Administrator’s Guide.

Symantec NetBackup for Oracle Advanced BLI Agent uses Storage Checkpoints

to enhance the speed of backing up Oracle databases.

See the Symantec NetBackup for Oracle Advanced BLI Agent System Administrator’s

Guide.

For more information about the implementation of Storage Checkpoints, see the

Veritas File System Administrator’s Guide.

Veritas FlashSnap Agent for Symmetrix

The EMC TimeFinder product from EMC is a business continuance solution that

allows you to create and use copies of EMC Symmetrix devices while the standard

devices remain online and accessible. Business Continuance Volume (BCV) devices

contain copies of Symmetrix standard (STD) devices and provide redundancy.

You can temporarily detach the BCV mirrors and use the BCVs to perform backups,

testing, and other administrative tasks.

Veritas FlashSnap Agent for Symmetrix provides a set of commands that allow

you to use the EMC TimeFinder split and restore operations in conjunction with

VxFS file systems and VxVM disk groups and volumes that have been created on

Symmetrix STD devices.
