If your data center or
computing environment requires recovery to a specific point in time
(not just to the most recent valid backups), you can set up a
process that ensures that you can recover both the NetBackup
catalog and the data for that specific time. You should retain the
corresponding catalog backups for the same length of time as the
corresponding data backups.
The following high-level
information is intended as an overview of how to archive the
catalog and data so you can recover to a specific point in time.
Detailed instructions for accomplishing all the tasks necessary are
Before you can recover to
a specific point in time, you must archive the catalog and
To archive the catalog and data
Use your normal
procedures to vault the data and NetBackup catalogs for that
Use the bpmedia command to freeze the data and catalog
volumes that you want to retain.
Freezing the volumes
prevents them from becoming unassigned and from appearing on the
Picking List for Vault report. Do not recall the volumes from
off-site storage when they expire.
Vault a printed copy of
the Recovery Report for that specific point in time.
You will need the
Recovery Report from the specific point in time so you can recall
and restore the appropriate catalog and data volumes.
Optionally, remove the
media IDs from the volume database.
This reduces the size of
the database and improves performance. Depending on the number of
volumes, maintaining the media IDs in the volume database may not
degrade performance much.
To recover the catalog and data
Retrieve the appropriate
printed Recovery Report from off-site storage.
Using the Recovery
Report, recall the appropriate catalog backup and data volumes from
off site storage.
Recover the catalog that
you recalled from off-site storage.
That version of the
catalog contains information about the archived volumes and the
images on them.
Use the bpexpdate command to reset the expiration date on
the recalled volumes so they are not expired. Use the -policy option to change the expiration date for
all media associated with a specific policy.
Change the images to be
recovered to primary (NetBackup restores from the primary
To change a large number
of images to primary, use bpchangeprimary
-group option to specify all images in a specific off-site
For information about the
bpchangeprimary command, see the
NetBackup Commands for UNIX or NetBackup Commands for Windows guide.
Restore the data.
The NetBackup Administrator's Guide, Volume I includes
an alternative procedure for archiving the catalog. That
alternative procedure uses the catarc
catalog archive policy to archive old data in the NetBackup
catalog. You can then vault the archived catalog data or a copy of
the archived catalog data.
