Testing, Testing and More Testing!! Testing Your Recovery Strategy Ensures You Have a Good Backup Strategy!! Your Backups are only as Good as Your Recovery Only True Backup Verification is Done by Testing Your Recovery Recovery Strategy only as Good as Backup Strategy Design Recovery Strategy Before Backup Strategy

Prevent Disasters Before Test! Don't forget keys to vital records boxes Know your password Keep passwords current Arrange for serial number dependent software Use PRTSYSINF Command or option on Save Menus 21, 22 and 23 (V4R2 or later) to print important system information Ensure RSTLIB and CHGPWD commands NOT changed to use different programs

Prevent Disasters Before Test! Tape Management Ensure tapes are labeled or cataloged with unique volume IDs (Tape Management Product such as BRMS) Prevent overwriting tapes with active data (tape management product such as BRMS) Have at least two sets Use error reports to remove bad tapes from inventory Audit tapes for data integrity Do NOT IGNORE tape drive problems!

Prevent Disasters Before Test! Ensure Critical Data is Completely Backed Up!! Completely back up Library QUSRSYS #1 recovery problem today!! Objects starting with Q in QUSRSYS contain critical recovery data To Save Everything in QUSRSYS: End all subsystems (with ENDSBS SBS(*ALL)) Ensure subsystems QSNADS, QSYSWRK, QSERVER ended & ENDTCPSVR *MGTC Use Save menu option 21 or 23 Use the save-while-active feature

Prevent Disasters Before Test! ALWAYS Save Access Paths! Default on Save Menu Options (21, 22, 23) is YES to Save Access Paths Default on BRMS is YES to Save Access Paths BEWARE!! Prior to V5R3 Default for Saving Access Paths on Save Commands is NO

Saving Access Paths - New Default for V5R3 New Save Access Paths Default for Save Commands *SYSVAL New System Value QSAVACCPTH '1' Save Access Paths (Default) '2' Do Not Save Access Paths Supported on SAVLIB, SAVOBJ, SAVCHGOBJ, SAVRSTLIB, SAVRSTOBJ, SAVRSTCHG *YES or *NO Still Valid Options

Recovering with Alternate Installation Device Allows Setup of Alternate Installation Device for Alternate IPL REQUIRED for FIBRE CHANNEL TAPE DEVICES! Define Via Dedicated Service Tools (DST) NOTE: Alternate Installation Device REQUIRES PID Install CD for Installs and System Recoveries from Tape Media

Prevent Disasters During Test! During Install/Restore On RISC, Install Licensed Internal Code using option 2 - Install Licensed Internal Code and Initialize system (unless system pre-configured and instructed to select option 3 to Recover Configuration) Enter the Correct Date Enter Correct System Time Zone (New for V5R3)

Prevent Disasters During Test! System Values Settings Required Recovery System value QALWOBJRST must be *ALL System value QJOBMSGQFL must be *PRTWRAP System value QVFYOBJRST must be 1 (V5R1 and higher) Security Sensitive System Value Changes Not Allowed DST Option in V5R2 Default is to Allow Changes If Disallowed, Must Update in DST to Allow Changes During Recovery

Prevent Disasters During Test! Recovering to a Different System (Different Serial Number) Must specify ALWOBJDIF(*ALL) on all RSTxxx Commands - MBROPT(*ALL) on RSTLIB Command Note: ALWOBJDIF(*ALL) during System Recovery to a Different System Links Authorization Lists to the Objects Must specify SRM(*NONE) on RSTCFG command

Prevent Disasters During Test! Security Issues During Recovery After Restore, Unsure of QSECOFR Password? Not sure if password has Expired? Change Password (CHGUSRPRF command) before signing off Know Other User IDs needed for Test

Prevent Disasters During Test! Security Issues During Recovery Authorization lists securing objects in QSYS: Association between object and authorization list lost during restore because QSYS restored prior to user profiles Need program to produce a file of these objects and include file in the save (See An Implementation Guide for AS/400 Security and Auditing, for sample programs (ALLAUTL and FIXAUTL))

Prevent Disasters During Test! Need only Critical Application Data restored? You MUST restore libraries QSYS2, QGPL and QUSRSYS NOTE: Starting with V5R2 QSYS2 is part of *ALLUSR Saved with *IBM Save Previously SAVLIB/RSTLIB of *NONSYS or *ALLUSR in V5R3 Saves and Restores QSYS2, QGPL and QUSRSYS First If you use journaling, the libraries containing the journals must be restored before restoring the journaled files

Prevent Disasters During Test! If you have logical files whose based-on files are in a different library, you must restore all based-on files before you can restore the logical file Message CPF3204 "Cannot find object needed for file xxxx in xxx" During Recovery If RSTLIB(*NONSYS) Performed, Run the Following Command to Restore Logical Files RSTLIB SAVLIB(*NONSYS) DEV(media-device-name) OPTION(*NEW) MBROPT(*ALL) ALWOBJDIF(*ALL) Otherwise, Run the Following Command for each Logical File that Needs to be Restored RSTOBJ OBJ(logical-file-name) SAVLIB(library-name) DEV(media-device-name) OBJTYPE(*FILE) MBROPT(*ALL) ALWOBJDIF (*ALL)

How do I Get Started on a Disaster Recovery Plan? Appendix B - Backup and Recovery Book Example Disaster Recovery Plan

Rapid Recovery for iSeries and AS/400 Replication

iSeries and AS/400 Replication . . .a Rapid Recovery feature that enables you to replicate your applications and data. Can achieve recovery time objectives of minutes Protects data to last replicated transaction Uses tried and tested mirroring software, such as MIMIX from Lakeview, or OMS400 from Vision. These software products have been available for almost 10 years. System mirroring is the fastest recovery technique available today. Mirroring also ensures that your data is current and available at time of disaster, as opposed to the last backup. IBM Site Hotsite Customer Customer

iSeries and AS/400 Replication Options You can replicate all or part of your system to a target system at either hotsite or one of your sites. Customer Site Hotsite or Customer Site Customer Site Or you can replicate all or part of your system to a partition on a target system at a hotsite. This solution enables sharing of resources and achieves a new price point for replication. Customer Site(s) Customer(s) Hotsite We work with you to determine the best solution to meet your needs; Factors we take into account ; Your specific requirements and environment What to mirror, total system, critical applications, or just data What mirroring software Dedicated target system or partition. Mirroring network & recovery network . CATS software from Silverlake Technology, or Logical Partitioning from IBM enables many customers to mirror with the IBM system without any impact on the ability of each customer to switch production to the vault system. Partitioning

Remember.....Test Your Recovery!!! The Only Way to Ensure you have a Good Backup Strategy is to Test your Recovery!!!!
