Veritas Database FlashSnap helps to create a point-in-time copy of a database for backup and off-host processing. Database FlashSnap allows you to make backup copies of your volumes online with minimal interruption to users.
Veritas Database FlashSnap is included with Storage Foundation for Oracle RAC.
Database FlashSnap lets you capture an online image of an actively changing database at a given instant, known as a snapshot. You can perform backups and off-host processing tasks on snapshots while providing continuous availability of your critical data. Database FlashSnap commands can be executed from the command-line.
Veritas Database FlashSnap offers you a flexible way to efficiently manage multiple point-in-time copies of your data, and reduce resource contention on your business-critical servers.
Database FlashSnap allows database administrators to create a consistent copy of a database without root privileges by creating a snapshot. A snapshot copy of the database is referred to as a database snapshot.
You can use a database snapshot on the same host as the production database or on a secondary host sharing the same storage. A database snapshot can be used for off-host processing applications, such as backup, data warehousing, and decision-support queries. When the snapshot is no longer needed, the database administrator can import the original snapshot back to the primary host and resynchronize the snapshot to the original database volumes.
Database FlashSnap can significantly reduce the time it takes to backup your database, increase the availability of your production database, and still maintain your production database's performance.
Note
To use Database FlashSnap, you must have Storage Foundation for Oracle RAC on all systems on which you intend to use Database FlashSnap.
To use Database FlashSnap, you must first configure the volumes used by the database.
Note
For SF Oracle RAC database, when you issue the commands, replace $ORACLE_SID with $ORACLE_SID=instance_name and provide the instance name on which the instance is running.
