Golden Rules for Backup/Recovery

That Which Has Not Been Backed up Cannot be Recovered

That Which Has Not Been Backed up Offsite Will Not Survive a Disaster

Any Backup That Has Not Been Tested With a Recovery is Not a Backup

Back It Up or Give It Up

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


27/46


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


28/46



Tape Management

Ensure tapes are labeled or cataloged with unique volume IDs (TapeManagement 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!


29/46



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


30/46



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


31/46


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

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


34/46


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)


35/46



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


36/46



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


37/46



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


38/46



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))


39/46



Need only Critical Application Data restored?

You MUST restore libraries QSYS2, QGPL and QUSRSYS

NOTE: Starting with V5R2 QSYS2 is part of *ALLUSRSaved 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


40/46



If you have logical files whose based-on files are in a different library, you mustrestore all based-on files before you can restore the logical file

Message CPF3204 "Cannot find object needed for file xxxx in xxx" DuringRecovery

If RSTLIB(*NONSYS) Performed, Run the Following Command to RestoreLogical 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 tobe Restored

RSTOBJ OBJ(logical-file-name) SAVLIB(library-name) DEV(media-device-name) OBJTYPE(*FILE) MBROPT(*ALL) ALWOBJDIF (*ALL)
