IRIX NetWorker is an easy-to-use network backup and recover product. Every user knows about accidental file loss and hard disk crashes. With NetWorker, you can easily protect your valuable files from loss by performing backups as your needs dictate, in addition to the automatic backups scheduled by your system administrator. NetWorker allows straightforward recovery, which lets you find and retrieve lost files easily and quickly.
NetWorker allows fast file recovery, which means you do not have to waste time recreating lost files. Just scroll through the window of previously backed-up files to find the ones that were lost. NetWorker can list multiple versions of a file that were backed up over time and lets you select the ones you want to recover. NetWorker provides access to these powerful features through an intuitive graphical user interface.
The NetWorker server is a machine with a backup device that automatically backs up systems on a network. Once your system administrator installs NetWorker and configures the NetWorker server to recognize your system as a NetWorker client, your files will automatically be backed up to the NetWorker server. However, you can request NetWorker to back up important files at any time.
When you use NetWorker to back up your files, you are saving them to a backup volume on the NetWorker server. The NetWorker server keeps an online index of the backed-up files for you to browse when you want to recover a single file or a complete directory.
After the NetWorker client software is installed and enabled on your system, as described in the next section, the system administrator will configure the NetWorker server so that you can use the backup and recover services.
Follow the procedure in this section to install Networker client software. Because licenses for NetWorker clients are not installed on the clients, no enabling of the client software is required.
On the client, become root and give the inst(1M) command:
% /bin/su - Password: # inst |
Specify the location of the NetWorker software distribution and get a list of the subsystems, for example:
Inst> from /CDROM/dist Inst> list |
For additional information on inst, see the IRIS Software Installation Administrator's Guide.
Make subsystem selections in inst. Use Table 1-1 to guide you in selecting subsystems. Subsystems not listed in Table 1-1 should not be installed on clients. For example, to install the required software, references pages, release notes, and InSight versions of the NetWorker manuals on an IRIX 5.3 client, give these commands:
Inst> keep * Inst> install networker4.*.client_5 Inst> install networker4.man.relnotes Inst> install networker4.books.* |
For additional information on these subsystems, see the IRIX NetWorker Release Notes.
Table 1-1. Subsystems for NetWorker Clients
Subsystem | Description | Required/Optional |
|---|---|---|
networker4.sw.client_4 | NetWorker client software | Required (install on systems running IRIX 4.0.x only) |
networker4.sw.client_5 | NetWorker client software | Required (install on systems running IRIX 5.x only) |
networker4.man.client_4 | Reference pages for NetWorker client software | Optional (install on systems running IRIX 4.0.x only) |
networker4.man.client_5 | Reference pages for NetWorker client software | Optional (install on systems running IRIX 5.x only) |
networker4.books.NetWorker_UG | Optional on systems running IRIX 5.x; cannot be installed on systems running IRIX 4.0.x | |
networker4.books.NetWorker_AG | The InSight version of the IRIX NetWorker Administrator's Guide | Optional on systems running IRIX 5.x; cannot be installed on systems running IRIX 4.0.x |
networker4.sw.archive.client_5 | Optional archive and retrieve client software | Requires purchase of TurboPak option |
Perform the installation and exit inst:
Inst> go Inst> quit |
Check to see if the hostname alias nsrhost has been set to your NetWorker server:
jupiter% /usr/etc/ping -c1 nsrhost PING mars.engr.xyz.com (192.48.155.20): 56 data bytes ... |
In the command, the -c is followed by a 1. The first line of output should contain the name of the NetWorker server.
If the output doesn't contain the name of the NetWorker server, the networker command won't automatically connect you to your server; you'll have to use the “Change Server” command on the File pulldown menu to specify your server.
To set the hostname alias nsrhost to your NetWorker server, follow the directions in the section “Configuring Clients to Recognize the Server” in Chapter 2 of the IRIX NetWorker Administrator's Guide or ask your system administrator to help you.
