Protecting and Recovering Data: An Overview

Before you learn the details of protecting and recovering your data, read the following scenarios for protecting and recovering data. These scenarios are presented in detail in "Backup and Recovery Scenarios".

Protecting Your Database and Storage Pool

1. Create a copy storage pool

2. Do a full backup of the primary storage pools to the copy storage pool

3. Do the following daily:

   1. Do incremental backups of the primary storage pools to copy storage pools

   2. Back up the database

   3. Save the volume history file (which describes ADSM volumes) the device configuration file (which describes the devices ADSM uses) and your server options

   4. Move offsite: copy storage pool volumes, database backup volumes, the volume history file, the device configuration file, and your server options

Recovering to a Point in Time

1. Install ADSM on a replacement processor

2. Move the database and storage pool backup volumes onsite

3. Restore the database from the latest backup level

4. Audit storage pool disk volumes and any tape volumes that were reused or added since the last backup. This information is recorded in external files that have been defined in the VOLUMEHISTORY option of the server options file for storing volume history information.

5. Delete from the database any volumes in the copy storage pool that were onsite at the time of the disaster

6. Define new volumes in the primary storage pool

7. Restore the primary storage pool volumes from those in the copy storage pools

Recover a Lost or Damaged Storage Pool Volume

1. Identify the copy pool volumes containing backup copies of the files in the lost or damaged volume

2. Mark the copy volumes as unavailable

3. Bring the copy volumes onsite and mark them as read/write

4. Restore the destroyed files

5. Mark the copy volumes offsite and move them offsite
