    Google "iSeries save entire system". You will get many responses.

    Generally we follow 3 steps.

    1. End all subsystems (ENDSBS SBS(*ALL) DELAY(600))
    2. From a command line type go save, take option 21.
    3. Restart the system (PWRDWNSYS RESTART(*YES))

    We (over) engineered a few CL programs to do a full backup at 23:45 every Sunday, then eject the tape and restart the system. The only pre-condition was that an operator had to sign on to the console at some point during the week as a "Save Control" user that had a specific sign-on program. Our scheduled day-end job sends a message to this sign-on program telling it to start the whole shutdown-save-restart process. Backups happen while you sleep. :-)

    We also used to do the System Save via the Console that was ready to receive the trigger to start the system shutdown to restricted state (required for System Save) take the Backup and IPL the system. Since we use BRMS we use that to launch the console job.

    If you have a tool like BRMS or Robot Save or something else, use that tool.

    We do a full system save every night. (no tools)

    On the console:

    (user profile must have enough authority to perform backups)

    on a command line- Go Save <enter>

    21 <enter>

    verify the paramaters on the screen (restart, time to start the backup, etc.)

    press enter.

    This will end the subsystems, perform the backup and initiate the QSTARTUP routine (check the system value for the program and look at the  source to see what happens in the start up routine).  We have a few jobs that start off the system job scheduler in the event some one forgets to set the back up.

    @azohawk: Any large site wouldn't dream of attempting a "full system save" every night, most likely not even over night. Only the smallest sites would consider doing that. And it's generally a waste of time, so it's only rarely (once a year?) worth doing... for perhaps most sites.

    How often do you test those backups? Restoring from them every once in a while could show that a more appropriate save strategy would be much more useful.

    @rajasekarsrm40: The Backup and recovery topic in the Knowledge Center for your system type and OS version is where you need to look. We'd need to know a lot more details about your system environment to know what steps you should take.
