BackBox H4.00 User Manual

Product Description
33 BackBox H4.00 User Manual
A RESTRICTED Data Store promoted to PRIMARY replaces the original owner, in a
site or environment recovery.
When a RESTRICTED Data Store is promoted to PRIMARY domain access, the
volumes of the Data Store will progressively migrate to the full Primary domain
access state, as they are rewritten for backup by the new Owner domain.
Note that when a PRIMARY Data Store is changed to RESTRICTED, then changed
back to PRIMARY less than 24 hours after, there is no progressive migration: all
volumes are considered immediately migrated.
After a volume is migrated:
The next load will be controlled by the volume timestamp – if enabled
by the Data Store configuration
The next access will be authorized by the security setting registered in
the domain catalog.
While volumes are not migrated, they are managed as Restricted:
There is no control of volume timestamp
The authorizations displayed in the BackPak GUI looks like: “??N”. The
two ‘?’ indicates that READ and WRITE access will be checked
according the settings saved at backup time as metadata in the tape
volume image.
The user can override the security settings by specifying regular
authorization (such as N, O, G…) for READ and WRITE access, and
revising the ownership displayed in the same volume detail page.
Secondary Data Stores and Catalog replication
To prepare a Disaster Recovery, virtual tape volumes must be saved, backed up or
replicated. The tape catalogs on NonStop (BackPak catalog, DSM/TC catalog …) must
also be saved.
The virtual tape volumes are saved by means specific to the storage that holds
them: HP StoreOnce, Tivoli Storage Manager (IBM/TSM), Data Domain, disk arrays,
have their own way to duplicate the objects representing a tape volume. BackPak is
not involved in this data replication, except when the replication is obtained by
triggering backup script when virtual volumes are written.
With the D/R license option, BackPak replicates the entries in the BackPak and
optionally DSM/TC catalogs, saving immediately after each backup the associated
catalog changes to the secondary site.
QTOS, CA and TMF catalogs cannot be duplicated. For environments using these
catalogs, only the BackPak catalog will be replicated from the primary to the
secondary side.
