System Restoration Methods

You can restore your system in two ways: By entering the restore commands listed on the System Restoration report on a command line or by selecting restoration procedures from the Guided System Restoration Procedures panel. The System Restoration Checklist topic provides step-by-step instructions for restoring your system.

Using the Restoration Reports

Robot Save automatically prints out the following restoration reports after every backup:

Restore your system if you have lost all disk drives The instructions list the commands needed to restore the last entire library saves from tapes. Then, the report lists commands to restore the library changes since the entire library save was done.

Restore your system if you have lost a disk drive but your save file ASP is intact

The instructions list the commands needed to restore from available library save files and then from tapes for the rest of the items.

Restore your system from your previous set of media volumes The instructions list the commands needed to restore from the last pre- ceding saves. You can use these restoration instructions in combination with the above instructions if you have had a partial tape loss.

Restore your system and replicate your current system configuration The instructions list the commands needed to restore your system with only the items that were on the system at the time the report was run. For example, if you run a backup, delete items, then run the report, the report shows the system configuration when the report was run, not at the time of the backup.

To restore your system, locate the volumes indicated on the appropriate restoration report. Then, type in the commands on a command entry panel. You can print the restoration reports for the most recent save at any time by selecting option 3, System Reports, from the Automated Backup Setup Menu. You also should have copies of the Audit Report (RBS405) and, if you use object lists, the Saved Object List Contents Report (RBS407).

Using the Guided System Restoration Procedures Panel

The Guided System Restoration Procedures panel lists the procedures necessary to restore your system. If save files are on an undamaged ASP, Robot Save also lists them. To display the Guided System Restoration Procedures panel, enter option 4 on the Automated Backup Setup Menu.

You can select to restore one library, several items, or all the items listed on the panel. When you select the items to be restored, Robot Save specifies the media volumes you need for the restoration. During the restoration, Robot Save tells you the proper volume to mount. If you have selected to restore more than one library, Robot Save determines the most efficient order in which to restore the items based on the user- defined sequence and the media volumes where they were saved. This helps make the restoration process more efficient by minimizing tape mounts and tape rewinds. Finally, Robot Save tells you whether or not the restore was successful.

Robot Save guides you through the restoration procedures until the entire system is restored. If necessary, you also can restore a library from a save other than the last save of the entire library or its changed objects.

Note: If you plan to restore your system using RSTLIB *NONSYS, you should restore the Robot Save libraries (RBSDTALIB, RBSPGMLIB, and RBSKEYLIB) first.
