Chapter 3: UNIX Disaster Recovery

Task 1: Install the NetWorker Storage Node

To install the NetWorker storage node software:

 

1.

Install the same version of the NetWorker storage node software into its

 

 

original location.

 

Note: If you want to upgrade the storage node software, first recover the

 

storage node to its original state, and then perform the upgrade.

 

2.

Install any NetWorker backup utility patches that were installed prior to

 

 

the disaster.

 

3.

Re-create any links to NetWorker directories.

 

4.

Optionally, use the nwrecover program to perform a test recovery to

 

 

ensure that the recovery process is functioning properly.

Note: The NetWorker client software is also installed when you install the

storage node software.

The storage node can now access volumes that contain backups for other computers on the network. These volumes contain the application and user data that are required to fully recover computers that were protected with the NetWorker client software.

If you want to recover the application and user data for other NetWorker clients, see “Recovering a NetWorker Client” on page 43.

If you want to recover application and user data that was on the storage node computer, see, “Task 2: Recover the Application and User Data” on page 41.

Task 2: Recover the Application and User Data

To recover the application and user data that was on the NetWorker storage node computer:

1. If you need to determine which volumes contain the application and user data backups for this computer, use the mminfo -avotcommand on the NetWorker server, for example:

#mminfo -avot-cstorage_node_name

where storage_node_name is the hostname of the computer whose application and user data you are recovering.

2.Start the nwrecover program on the storage node computer.

3.Mark all of the directories and files that you want to recover.
