Removing the detail catalog

When the detail catalog is removed for a specific medium, its DC binary file is

removed. The same result is achieved by removing the catalog protection for all

object versions and object copies on that medium (the next daily maintenance of DC

binary files removes the binary file). All other records stay in the CDB and MMDB

and it is possible to run a restore from such media (however, browsing is not possible).

Filenames purge

DC binary files show whether a given file is backed up on a related medium or not,

but the filenames are actually stored in the CDB. A filename is considered “used” if

it is marked as backed up in at least one DC binary file. Over time, it can happen

that a large number of filenames are not used. To remove such filenames, Data

Protector scans all DC binary files and then removes unused filenames.

File versions purge

When the catalog protection of all object versions stored on a specific medium

expires, automatic daily maintenance of DC binary files removes the respective binary

file.

Overview of IDB management

IDB configuration

One of the most important steps in setting up your Data Protector backup environment

is to configure the IDB. The initial configuration enables you to set your internal

policies regarding IDB size, the location of IDB directories, the IDB backup necessary

in case of IDB corruption or a disaster, and the configuration of IDB reports and

notifications.

IMPORTANT:

It is highly recommended to schedule an IDB backup to be performed on a daily basis.

Creating a backup specification for the IDB backup is part of the IDB configuration.
