Backup and Recovery

Always perform a backup of the system before making patch-related system changes. You should have a backup in the event that unacceptable behavior occurs as a result of patching.

This section provides some resources that you can investigate for recovery strategies. It does not provide the details needed for recovering from patch-related problems.

HP Ignite-UX (IUX)
- IUX is a set of tools that you can use for system installation, recovery, and duplication.
- The make_net_recovery andmake_tape_recovery features of IUX can be good starting points for investigating IUX recovery tools.
- See the Ignite-UX: Summary page at http://docs.hp.com/en/IUX.

Considerations

You should have a detailed recovery plan formulated before you install anypatches.
You should know how long the system can be down for patch installation, and setaside a portion of that time for recovery in case it is required.
When patching critical systems, some customers have a redundant environment inplace to take over in theevent that anything goes wrong with the production system.
If you install patches with patch rollback files, then patch rollback will be an option if there are problems with the patch installation. See “Patch Rollback and Commitment”.
