About this document

These procedures assume the following conditions exist:

This document applies to AIX Versions 3.2.5 and later running AIX System Backup and Recovery/6000 Versions 3.x and later.


Configure the server for remote backups

To perform a remote backup, use SMIT to set up the Sysback remote services on our server machine.

Enter smitty sysback and select the following menus options:

   Configuration Options
     Remote Services
       Server Options
         Configure Remote Services

Allow access to the Sysback server

Next you must allow access to the server. You can choose to allow access by host name, or you can allow all hosts. Also, you can allow either root or all users. Next, a menu will come up with the current settings and more options. You can allow specific devices, or "all" devices. Finally, if you want to allow backups to disk, you can specify the directories for this.

Enter smitty sysback and select the following menu options:

   Configuration Options
     Remote Services
       Server Options
         Add a Remote Client
Complete the Add a Remote Client fields as follows:


Configure the client for remote backups

For a client to be able to perform network backup and recovery, it must have its remote services enabled.

Enter smitty sysback and select the following options:

   Configuration Options
     Remote Services
       Client Options
         Configure Remote Services

Add a server to the client's list of backup servers

Now that remote services are enabled you need to tell the client which servers are OK to use:

Enter smitty sysback and select the following options:

   Configuration Options
     Remote Services
       Client Options
         Add a Remote backup server


Verify configuration

Sometimes the configuration does not result in complete communication. You should verify that communication exists between the client and server. If this fails, there could be a DNS or /etc/hosts discrepancy including multiple lines for the same host or IP, or non-matching reverse DNS. Sysback is very particular about this; upper and lower case will make a difference. Also, some earlier versions of Sysback were not too happy going through a firewall. To verify communication, do the following:

  1. Log on to the client.
  2. Enter smitty sysback and select the following menu options:

       Configuration Options
         Remote Services 
           Client Options
             List Remote Backup Servers
    
  3. If this hangs or otherwise fails to list your server and its devices, enter the following command to remove Sysback:
    /usr/lpp/sysback/rmsysback
    
  4. Re-install from your source media. Then follow the instructions in this document again. No customized Sysback user files will be affected so long as the usr/lpp/sysback directory is not deleted or moved before reinstallation of Sysback.
  5. If Sysback still fails at this point, contact your AIX support center for troubleshooting assistance.
