You have been able to do unattended backups for some time using BRMS and the
console mode, you don't need to be at V5R4. I have one of my clients set
up, where we go into Console mode, and they then leave. There is a job on
the standard job scheduler that submits, and then BRMS does a full system
save.
Since when does *ALLUSR need to be in restricted state? I have been using
that for 17 years, and it does not require a restricted state. It's for
that reason that I like using both *ALLUSR and *IBM as neither will require
a restricted state. *NONSYS requires a restricted state.
In addition, you can use Save While Active. I have accounts where we are
backing up using BRMS, Save While Active, almost 1.6 TB of data each night,
and we have very LITTLE downtime.

We're using BRMS to handle our saves to a tape library.
Currently, we save the complete IFS, and *ALLUSR libraries every night (yes,
that means restricted state - so it's also V5R4 only).
Every Sunday, we do an automatic unattended save 21 equivalent using BRMS
(only possible on V5R4). After that the System IPLs.
Yes, this methodology brings a lot of downtime with it, and i would like to
do all my backups online - but's currently not possible with i5/OS.
SWA seems to be something done _really_ halfway, as it is a giant hassle to
restore and get to work. Gotta love Windows's Shadow Copy Backups.

Subject: Backup strategy
We're currently reviewing our backup strategy.
What I would be interested to hear is how other shops handle the QUSRSYS
library.
- Do you back it up as part of your nightly saves?
- If not, how often do you back it up?
- How do you back it up?
(e.g. SAVE21 only, SWA, or shutting down everything holding locks
within it, then SAVLIB)?
Somewhat related: Job Q1PSCH (PM/400 scheduler) is holding a lock within
QUSRSYS. Is there an easy way to stop/start this job for backup purposes?
Thanks,
Moe
