Managing Snapshots with Database FlashSnap
With VERITAS Database FlashSnap, you can create a point-in-time copy of a database for backup
and off-host processing. For more information, see “Using Database FlashSnap for Backup and
Off-Host Processing” on page 197.
From the GUI, you can create snapshots of your database using snapplans. You can also
resynchronize snapshots to your database and your database to a snapshot. The following sections
describe the Database FlashSnap features within the GUI.
Database FlashSnap functionality is not supported on duplicated (cloned) databases.
Prerequisites
◆ Before you can create a snapshot, a snapshot mirror of a volume must exist. For details, see
“Creating a Snapshot Mirror of a Volume or Volume Set Used by the Database” on page 206.
Creating a Snapplan
A snapplan specifies snapshot scenarios for an Oracle database (such as online, offline, and
instant). The snapplan is used as a basis for creating a snapshot. You must either create or validate a
snapplan before you can create the snapshot image.
Prerequisites
◆ You must be logged in as the Oracle database administrator.
◆ The disk group must be version 110 or higher.
◆ Persistent FastResync must be enabled.
◆ To set up your snapplan for online snapshots, the database must be in archive log mode.
Usage Notes
◆ Database FlashSnap functionality is not supported on cloned (duplicated) databases.
◆ The snapplan name is user-defined.
◆ Each entry in the snapplan is a line in parameter=argument format.
◆ See the dbed_vmsnapplan(1M) and dbed_vmchecksnap(1M) manual page for more
information.
