RE: BRMS Backup Strategy and Implementation



fixed

Rob,

Do you use append?
Do you dup all your saves?

We don't want perm saves mixed with saves that expire, etc.
Still using all one scratch pool, when a volume becomes active the media/move policy for that save/control group is assigned to that volume, then only the same save will be appended to that volume.
Prior to doing this, when our saves expired, we ended up with many volumes with only a few items on them, so the volume would never expire.
That's our reasoning.

Paul

Yeah, too many people try to use BRMS to duplicate their old way of thinking, with meaningful tape volume names, etc.

As I said ealier, I also don't allocate tapes to different retentions. It grabs a tape from the library and assigns it the retention I want for this backup.

WRKPCYBRM contains items like

Rob,

I was happy to see your comments about pulling tapes from one big pool.

I need to set up BRMS here as well. I wanted to have one tape pool across
two lpars and different types of save. I was told by a BP that I needed to
allocate tapes to specific save pools (for want of a better word). i.e.
These tapes are for Monday's development save, these are Monday's
production and so on.

I'm glad I can go back to my original 'vision'.


Gord

We also have different retention policies. Monday is kept for 'weeks'.
Other days for 'days'. Quarterly for a year.
We don't care if BR0204 expires off of a daily save and gets used in a
Monday or Quarterly save. Makes no difference to us. WRKMEDBRM will
show
us when the tape was used and when it will expire. WRKOBJBRM will show
us
what tapes it was saved on and when.

Rob,

Sorry for the confusion, currently only 6 scratch volumes, but normally
about 14.
Currently redoing a 10 year, 4 volume dup.
Our library has 45 slots, 1 reserved for cleaning, 3 I/O slots.
Currently 34 active volumes, probably about 10 different saves/control
groups.
We keep the this many active volumes in the library, most restores don't
require a media load, already in the library.
We run saves every day also, some saves have different retentions, so
the
combination of move/media policy will save/append to the correct volume.
We load / unload M-F.
I want to keep them balanced.
It's not really tricky the system, but keeping like saves on the same
volumes.

Paul

Only 6 volumes total? How many does your library hold?
Our library holds over 50 volumes. We load up a weeks worth at a time.
Actually 6 'run' days. We back up 5 days a week. The advantage to this
is it will still back up when the office is closed due to holidays or
snow
emergencies. Our library also has 18 I/O slots but don't let the number
of I/O slots limit you. We only run the *BALANCE once a week. Yes, we
remove the daily tapes every day but we only load new tapes once a week.

If you really are truly limited to 6 volumes, and you want two for one
and
4 for the other, then you should run the *SETs separately. One for 2
and
one for 4. But if your library holds a weeks worth then do a *SET for
(5
* 2) for the one and (5 * 4) for the other. Replace 5 by the number of
days of the week you back up.

You're not still trying to trick the system to use certain volumes on
certain days of the week, are you?

Rob,

To keep 2 LPARs balanced with the same number of owned scratch volumes,
would the below be the correct STRBALBRM strategy.

Currently Pencor05 owns 2 scratch ULTRIUM5 volumes, Pencor06 owns 4
scratch ULTRIUM5 volumes.

First, only once I would run
QSYS/STRBALBRM ACTION(*SET) MEDCLS(ULTRIUM5) LOC(TAPMLB01)
SYSNAME(PENCOR05 PENCOR06) MEDREQ(6)

Then daily, after loading scratch volumes into TAPMLB01, I would run
QSYS/STRBALBRM ACTION(*BALANCE) MEDCLS(ULTRIUM5) LOC(TAPMLB01)
SYSNAME(PENCOR05 PENCOR06)

Paul

And you only run STRBALBRM on one system. Or how you like to run it.

For example, if we have one tape library used in our Garrett IN office,
and that feeds multiple lpars, we may run the STRBALBRM on one of the
lpars there. And run a different STRBALBRM, once, on one of other lpars
in our Kendallville IN office for all of the lpars there.
