Barcodes And The Identify Job; Media Management; Import Media - HP BB118BV - StorageWorks Data Protector Express Package Addendum

Media Management

may be chosen for use in a job. This means that if a user is using barcodes with their tape
library, they will almost never need to run an identification job.
When the job loads the tape it makes sure that the tape is really what the catalog says it is
and, if necessary, updates the catalog to indicate what is really there. If the tape is, in fact,
not usable because of the supplied media rules, the tape is re-stowed and another media is
tried.

Barcodes and the Identify Job

An Identify job will always physically mount media, and re-associate media to barcodes.
This provides a mechanism for users to update barcodes on their media, should they ever
need to. It also handles the case where barcodes are added to media after they have been
used without barcodes.
Media Management
There are no specific media tasks that must be carried out before you run the first backup
job. As long as you have loaded valid media, Data Protector Express will automatically
use it.
NOTE: Media is invalid if it has been used by another backup product, is dirty or has been
corrupted.
Similarly, if you are restoring data from media that is already within the Data Protector
Express catalog, there are no media management tasks. However, if you are restoring
media from a different domain, you must first import it so that Data Protector Express
can add the media to the database and associate all data objects on the tape with that
media.
For a detailed description of all media management jobs, please refer to the relevant
section of this guide. This section describes the following media management jobs that
are appropriate to tape libraries:
Import Media, used to add media to the catalog (this job applies to all devices, not
•
just tape libraries).
• Sort Media, used to sort the media in a library.
• Insert Media, used to load media into the library from a mail slot.
• Remove Media, used to remove media that is to be removed from a mail slot.

Import Media

Each piece of media has two elements; the media object record which is its unique
identity within the Data Protector Express catalog and the data objects associated with it.
Data Protector Express cannot do any processing with the data objects, if the media
object record has been deleted from the catalog, is corrupted or missing. The Import
Media job creates a record for the media object in the catalog and associates the data
objects on the media with that record. You must run this job if you are restoring data that
was backed up on a server on a different domain or if you are restoring data on a media
that has been deleted from the catalog. The media must be in Data Protector Express
format for this job to run successfully.
