About off-host processing solutions
Off-host processing lets you implement the following activities:
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.
Data backup
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.
Decision support
analysis and
reporting
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.
