About restoring individual files from a NetBackup for SAP snapshot backup
Data that is backed up with Snapshot Client methods is restored in the same way as data that is backed up without Snapshot Client methods.
Use this procedure for the files that were backed up with, or without, instant recovery enabled. In all cases, SAP determines the files that were backed up, and it initiates a corresponding restore request to the database agent.
If instant recovery is enabled, NetBackup attempts to restore the file by using the unique restore methods available with the instant recovery feature. The type of restore method that NetBackup uses depends on your environment and the type of backup performed. If NetBackup is unable to use any of the instant recovery methods, it restores the file in the typical manner. Data is copied from the snapshot to the primary file system. Information on the instant recovery methods that NetBackup uses is available.
