You can verify the databases in your SnapManager backup sets immediately after creation, at a scheduled time later, or when you restore them.
By default, SnapManager automatically verifies full backup sets at the time the backup is created. This is simple and ensures that each database in the backup set is verified. However, this method significantly increases the time required to complete the backup.
You can start an operation to verify the databases contained in one or more backup sets that have already been created. You can start the verification immediately, or you can schedule the verification to occur later, when it does not affect performance or delay later backups.
If you attempt to restore from a backup set on which a database consistency check has not been run successfully, SnapManager prompts (but does not require) you to first verify the databases in that backup set.
