About NetBackup for Oracle restores of volumes and file systems using snapshot rollback
You can request that an entire volume or an entire file system be restored from an instant recovery Snapshot backup. This type of a restore is called a point in time rollback. All the data in the snapshot is restored; single file restore is not available in a rollback.
The following considerations are relevant for NetBackup for Oracle restores:
Snapshot rollback overwrites the entire volume.
With NetBackup for Oracle, snapshot rollback always performs file verification. The agent checks for the following:
The requested files (number and names) are identical to those in the snapshot
The primary volume does not contain any files that were created after the snapshot was made
If verification fails, the rollback aborts with status 249.
