Planning to Use Database FlashSnap
Before using Database FlashSnap, you must first determine your intended application.
You will then need to make the following decisions:
• Which snapshot mode is appropriate: online, offline, or instant?
• Will you need one or two hosts?
Selecting the Snapshot Mode
If your purpose is to use the snapshot for backup or to recover the database after logical
errors have occurred, choose the online option. In the event that your production
database is offline, choose offline. If you intend to use the snapshot for decision-support
analysis, reporting, development, or testing, choose instant. An instant snapshot is not
suitable for recovery because it is not necessarily an exact copy of the primary database.
