Data backup
|
As the requirement for 24 x 7 availability becomes essential for many businesses, organizations cannot afford the downtime involved in backing up critical data offline. By taking a snapshot of the data, and backing up from this snapshot, business-critical applications can continue to run without extended down time or impacted performance.
|
Decision support analysis and reporting
|
Because snapshots hold a point-in-time copy of a production database, you can set up a replica of the database using the snapshots. Operations such as decision support analysis and business reporting do not require access to up-to-the-minute information. They can use a database copy that is running on a host other than the primary. When required, the database copy can quickly be synchronized with the data in the primary database.
|
Testing and training
|
Development or service groups can use snapshots as test data for new applications. Snapshot data gives developers, system testers and QA groups a realistic basis for testing the robustness, integrity, and performance of new applications.
|
Database error recovery
|
Logic errors caused by an administrator or an application program can compromise the integrity of a database. By restoring the database table files from a snapshot copy, the database can be recovered more quickly than by full restoration from tape or other backup media.
