Using Backup Express for GuardianOS
112 Snap Server Administrator Guide
Managing the Catalog
Because the catalog tells you which tape contains the most recent version of a file, it
is vital that you back up the catalog regularly. Restoring your system in the event of
a severe system failure will be arduous and time-consuming without a usable copy
of the catalog. Without the catalog, you will have to rely on manual tracking of
backups.
Tip
The Snap Server is preconfigured with a single volume. The catalog resides in a
hidden portion of this volume. If you delete this volume, the catalog information
will be lost. In addition to regular catalog backups, be sure to backup the catalog
before reconfiguring a Snap Server.
To back up the catalog

Prepare the backup media.
Manually load the tape on which the catalog is stored to the appropriate device.

In the Backup Express GUI, navigate to the Backup Definition screen.
On the Administrator Menu, click Backup.

and location of its catalog.

<Backup Catalog>
to populate the Destination
window with media icons. Double-click any of these icons to open the

run at a later time, click the

this information by navigating to the Administrator Menu and clicking the

catalog backup job.
