Set Up for Recovery
This section suggests backup procedures for the BackBox environment. The recovery
procedures are detailed in the Operation Chapter.
When planning for recovery of a BackPak environment in the event of a site disaster
or a simple file loss, three groups of BackBox data must be considered:
1. The metadata on NonStop server(s): the BackPak Domain Manager
configuration, its catalog and one or more EMS Extractor configurations.
2. The configuration data kept in the BackBox VTC(s),
3. The images of virtual tape volumes kept in Data Store(s).
This related data must also be considered:
1. The tape catalogue, such as DSM/TC.
2. The configuration of the storage for the Data Stores, such as NAS with de-
duplication and replication
3. The security setup for accessing the storage, that can reside outside the
storage engine, in a Windows Access Directory for example
In a BackPak multi-domain environment, the data and metadata of each domain
must be recovered separately.
The BackPak Catalog Sync Option handles the replication of the volumes metadata
for the BackPak catalog (VOLUME* files), and the DSM/TC catalog. Please refer to
the BackPak Catalog Sync Option manual for this catalog replication.
With the Catalog Sync Option, the scope of recovery of the catalog is the part of the
catalog corresponding to a Data Store. The replication is an on-going replication of
new/modified entries operated in a Data Store. The unit of recovery is not
necessarily a BackPak Domain
Without the Catalog Sync Option, the BackPak VOLUME & VOLUME0 can only be
backed-up and restored globally, by tools such as BACKUP/RESTORE or generic file
replication tools. So the scope of a recovery is necessarily a full BackPak Domain,
additional BackPak Domains dedicated to recovery might be required.
