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 -avot command on the
NetWorker server, for example:
# mminfo -avot -c storage_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.
