1. The Data Domain system writes the backup image to the encapsulated storage
device, making it available on the primary storage array.
2. The Application Administrator mounts the encapsulated storage device to the
recovery host, and uses OS- and application-specific tools and commands to
restore specific objects.
Full-application rollback restoration
For a full-application rollback restoration, after selecting the backup image on the
Data Domain system, the Storage Administrator performs a restore to the primary
storage restore or production devices, depending on which devices need a restore of
the full database image from the chosen point in time. Unlike object-level restoration,
full-application rollback restoration requires manual SnapVX operations to complete
the restore process. To make the backup image available on the primary storage array,
the Storage Administrator must create a snapshot between the encapsulated Data
Domain recovery devices and the restore/production devices, and then initiate the link
copy operation.
The following image shows the full application rollback restoration workflow.
