About NetBackup for DB2 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.
You can perform a snapshot rollback from an instant recovery backup that was made with the following methods:
See the NetBackup Snapshot Client Administrator's Guide.
The following considerations are relevant for NetBackup for DB2 restores:
Snapshot rollback overwrites the entire volume.
With NetBackup for DB2, 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.
Use snapshot rollback with database files only. Database files and archive logs should exist on different file systems or volumes.
