AS/400 finds Objects
Note: Library Descriptions, Device Descriptions and User Profiles are
systems objects
and thus stored
in QSYS
. All other Object Types can be stored anywhere else Except for a

WHY ?
BACKUP
6
Backups and Restores
• Data may be lost for a variety of reasons and therefore you should be prepared (if necessary) to: – restore the
entire
system – restore security data, configuration objects, licensed programs libraries – restore any library or any object – restore any or all members of a file 7
Disaster Planning
• A disaster plan should be well thought out and well
documented
.
• A typical BACKUP plan might be to do
full backups once per week
and only backup
changes on a daily basis
.
• A RESTORE plan for this scenario would involve Step 1: restoring from the full backup Step 2: restoring from each of the changes backup to the time period desired.

BACKUP
– Tape or Savefile – All or Changes Only – Can be done while people are working
RESTORE
– Restore the most recent ALL backups of all libraries – Restore all of the CHANGES ONLY backups since the last ALL backup
REBOOT - IPL

When to back up?
Break the procedure up into manageable and practical lots and based on realistic and secure implementation.
System Configuration Libraries when it changes new release PTF’s -when it changes devices added network changed when updates received IBM licensed products Security data new users / reassignments user profiles authorizations OBJECTS - SAVCHGOBJ DAILY when changed 10
Create A BACKUP plan For Daily Weekly Monthly Quarterly requirements A dependable backup plan MUST ensure that
EVERY object
and category of object has been and is saved on a regular basis.

BACKUP MEDIA TAPE - DISKETTE - SAVF Before use initialize INZTAP - INZDKT To see the contents DSPTAP - DSPDKT - DSPSAVF or use the menu’s GO TAPE - GO DISKETTE - GO SAVE 12
Saving Data (backups)
• Go Save (menu) • Data can be saved to tape, diskette or a savefile.
• Commands: savsys, savlib, savsecdta, savobj, savchgobj, inztap, inzdkt –
SAVSYS
saves QSYS, licensed programs, security data, configuration objects –
inztap
and
inzdkt
are like the DOS “format” command 13
Some Save Commands •SAVSTG - saves every object on the system •SAVSYS - saves LIC, OS, and all security data •SAVSECDAT - saves all security data e.g USRPRF AUTL •SAVDLO - saves Document Library Objects •SAVLIB - saves “named” libraries •SAVCFG - save configuration (devices / lines / controllers + •SAVCHGOBJ - saves objects changed since last save function •SAV - can save the entire system - recommended for IFS only •Integrated File System 14

It is best to run backup with *SAVSYS authority For saving *SAVF files to tape you use the
SAV
SAVF
DTA
command A *SAVF must first be created using the
CRTSAVF
command before it can be used You can think of this as setting a part of the DASD (direct access storage device) aside and “initializing it” You can save any object to a save file. E.g. libraries, data files (generic grouping etc 16
RCLSTG
Reclaim storage
recovers all space in use by “FREE” objects objects with no library reference or not owned by ANY user ! TIME !
Clean up Remove objects that are no longer required Clear libraries -
CLRLIB
large dormant files -
CLRPF
leaves structures untouched 17
Preparatory Steps for a backup Initialize the media do cleanup tasks reclaim storage GO ASSIST or GO SETUP BACKUP tasks set up automatic scheduling
! *SAVSYS, Restrict access, notify everybody ‘SNDBRKMSG’ ENDSBS except QCTL
run the backup 18
Restoring Data
• Restore commands use saved data from backups to replace damaged or deleted objects.
• GO RESTORE - GO CMDSAV • Commands:
RSTLIB, RSTOBJ, RSTCFG, RSTUSRPRF, RSTAUT
19
Corresponding Save/Restore Commands Save Command Used SAVSYS Restore command to Use RSTOBJ RSTUSRPRF, RSTAUT RSTCFG SAVSECDTA SAVLIB SAVOBJ SAVCHGOBJ RSTUSRPRF, RSTAUT RSTLIB RSTOBJ RSTOBJ 20

Care & Maintenance of your AS/400
• Reboot! - IPL 23
Care & Maintenance of Your AS/400
• BACKUP – Tape or Savefile – All or Changes Only – Can be done while people are working 24
Care & Maintenance of your AS/400
• RECOVERY – Restore the most recent ALL backups of all libraries – Restore all of the CHANGES ONLY backups since the last ALL backup 25
Why do we IPL on the AS/400?
• Reclaim Space • Reorganize object pointers • Restore lost or damaged data • activate device configurations • implement PTF’s System values that influence the type/mode of IPL’s being done QIPLSTS , QIPLTYPE 26
PTF ‘s Program temporary fixes in between major operating system upgrades several temporary fixes or small upgrades can be released and accommodated this way.
CUM ‘s PTF ‘s cumulative HIPER PTF ‘s Hi-Impact and pervasive Follow the accompanying documentation to install any PTF Can be made permanent, some must be, but in general not recommended because they can not be reversed when applied permanently VERY HARDWARE MODEL DEPENDEND 27
