Data Backup

Before upgrading to a new version of NetWare, you should always make two or more complete, verified backups of both eDirectory data and file system data on your server. You can either use a NetWare solution or a third-party solution to back up the data.

TIP

Before using a third-party backup program, verify that it is fully SMS-compliant. (If you use an SMS-compliant backup program such as ARCserve, trustee information will be backed up.)


NetWare 6 contains a server backup feature called Storage Management Services (SMS). SMS consists of a set of programs that are both operating system independent and hardware independent. These programs allow you to back up and restore data across the network by using SBACKUP. SBACKUP can back up servers, workstations, or other services to media (such as tape, optical disk, or jukebox) for offsite storage. Examples of targets that can be backed up by using SBACKUP include eDirectory, binderies, the file system, cluster-enabled pools, or hard disks on individual workstations.

SBACKUP takes a snapshot copy of the data you select, stores a copy on tape (or other media), and then allows you to retrieve the data at a later time in case of a natural disaster, hardware failure, corrupted data, accidentally deleted data, and/or incorrectly changed data.

Even if you plan to use a third-party program to back up your data, you should be familiar with the procedures for using SBACKUP to back up (and restore) data on NetWare 4 and NetWare 5 servers.

Backing Up and Restoring a NetWare 5 Server

Before you backup your NetWare 5 server by using SMS, you should ensure that your system meets (or exceeds) all the SBACKUP system requirements, including NetWare 5 server with SMS installed, 3MB of available RAM (minimum), a host server with enough memory to run NetWare and connected clients, a target server, and, ultimately, a backup device.

To use SMS to back up data on a NetWare 5 server, perform these steps:

  1. Start at the server console. Load the device drivers for your controller and storage devices. If you load HAM drivers or add an external device, enter the following at the server console prompt: LIST DEVICES. Then, load the appropriate Target Service Agents (TSAs).

    TIP

    For more detailed information, refer to the section titled "Before Running the Backup Software" in the SMS manual at www.novell.com/documentation/lg/nw5/docui/index.html.

  2. Load the Storage Management Engine and backup software on the server. Begin by entering LOAD SMDR at the console. Accept the default or add an SMDR context by pressing Enter. Then, enter the full context of your username and provide your administrative password.

  3. Type the following commands at the console to activate SBACKUP:

     LOAD TSA500 LOAD SMSDI LOAD QMAN LOAD SBSC LOAD SBCON 
  4. After the NLMs are loaded, select Main Menu, Job Administration, Backup at the main menu. Next, choose the NetWare server running your backup or restore TSA by selecting Target Service. Enter the target username and password (if prompted) for the target.

  5. You will need to select what you want to back up. To do so, press Insert. On the NetWare server screen, select the volumes and files you want to back up, and then press Esc. In the Description field, enter a descriptive name for the backup session, and select Device/Media Name. Then, choose Advanced Options, Append Session. Finally, save your options and continue with the backup by pressing Enter. You can return to the main Menu by pressing Esc repeatedly.

To restore backed up data to a NetWare 5 server, perform these steps:

  1. Start at the server console. Load the device drivers for your controller and storage devices. Next, load the appropriate TSAs. Finally, load Enhanced SBACKUP.

  2. At the Main Menu, select Job Administration, Restore. Then, choose Target Service, NetWare Server Running Your Backup and Restore Target Service Agent. When you are prompted for the target username, enter your network administrator username and context (if required) for the target. If prompted, enter the password for the target.

  3. In the Description field, enter a descriptive name for the session. Select the device and media to restore. In the Device/Media Name field, press Enter and decide where you want to restore from. Then, select the session to restore.

  4. Finally, to make the selected restore, select Advanced Options, and complete the Advanced Restore Options form. Press Esc and answer the prompt at the Submit Job screen to begin the restore session. To view the activity log screen, press Alt+Esc. To return to the Main Menu, press Esc repeatedly.

Backing Up and Restoring a NetWare 4 Server

Before you use SMS to backup your NetWare 4 server, you should ensure that your system meets (or exceeds) all the SBACKUP system requirements, including NetWare 4 server with SMS installed, 3MB of available RAM (minimum), a host server with enough memory to run NetWare and connected clients, a target server, and, ultimately, a backup device.

To use SMS to back up data on a NetWare 4 server, perform these steps:

  1. Start at the server console. Load the device drivers for controller and storage devices. Then, load SBACKUP.NLM and the appropriate TSA files. On the host server, load the SBACKUP.NLM.

  2. From the Main Menu, choose Backup. Select a target for the data you want to back up. Next, choose the Backup/Restore Target Services Running on <Target Name> listing. Select the TSA you want to use. Then, provide the username and password for the target you want to back up.

  3. Select the device that you want to back up. Choose Type of Backup and highlight the type of backup you want to perform. Enter a description of the backup session. Save the description and continue with the backup by pressing F10.

  4. Finally, specify when you want the backup to start by setting the date and time for the backup to begin. Press F10, and save your changes by pressing Enter.

Before you attempt to restore data to a NetWare 4 server by using SBACKUP, you should ensure that you've met all the prerequisite system requirements: You must have Supervisor (or equivalent) rights, you need to know the username and password for the target server (or workstation) that you want to restore the data to, and you must be intimately familiar with the file structure of the data you are restoring.

To restore backed up data to a NetWare 4 server, perform these steps:

  1. At the server console, load SBACKUP. From the Main menu, select Restore. Select the target that you want to restore the data to, and enter the appropriate username and password.

  2. Specify how you want the date to restore. Then, start the restore by pressing F10. When you are done, you can view the error log to determine whether any files were not restored.
