IBM C2010-509 - Questions & Answers

You specify the number of days to keep backup versions with two parameters:

* Retain Extra Versions (how many days to keep inactive backup versions; the days are counted from the day that the version became inactive)
* Retain Only Versions (how many days to keep the last backup version of a file that has been deleted)

The Disaster Recovery Manager (DRM)
The TSM (Tivoli Storage Manager) Disaster Recovery Manager is a feature that is included with TSM Extended Edition and it is the part of the TSM application that can be used to assist with the management of off-site disaster recovery.

IBM Tivoli Storage FlashCopy Manager uses the copy services capabilities of intelligent disk subsystems to create point-in-time copies. These are application aware copies (FlashCopy or snapshot) of the production data. This copy is then retained on disk as backup allowing for a fast restore operation (Flashback).

* Access mode:
Defines access to volumes in the storage pool for user operations (such as backup and restore) and system operations (such as reclamation and server migration).

* Server processes can move files within the volumes in the storage pool.

* Data deduplication in Tivoli Storage Manager is a two-phase process. In the first phase, the server identifies the duplicate data in the storage pool. As volumes in the storage pool are filled, data becomes eligible for duplicate identification. A volume does not have to be full before duplicate identification starts.
In the second phase, duplicate data is removed by any of the following processes:

Reclaiming volumes in the primary-storage pool, copy-storage pool, or active-data pool Backing up a primary-storage pool to a copy-storage pool that is also set up for deduplication Copying active data in the primary-storage pool to an active-data pool that is also set up for deduplication Migrating data from the primary-storage pool to another primary-storage pool that is also set up for deduplication Moving data from the primary-storage pool to a different primary-storage pool that is also set up for deduplication, moving data within the same copy-storage pool, or moving data within the same active-data pool

* Example:

* The severity codes give an indication of the severity of the issue that generated the message. The severity codes and their meanings are as follows:
E Error Processing cannot continue.
W Warning Processing can continue, but problems may occur later. I Information Processing continues.
User response is not necessary.

The query inclexcl command displays a list of include-exclude statements in the order in which they are processed during backup and archive operations. The list displays the type of option, the scope of the option (archive, all, etc.), and the name of the source file.

RETOnly determines the number of days to retain the last Exchange Server database backup version of a database that has been deleted from the Data Protection for Exchange client system.

Tivoli Storage Manager provides two scheduling modes: client-polling and server-prompted.

Perform some file level restores of these backups using the Tivoli Storage Manager |Backup-Archive
