Re: Actual save time in BRMS?

Here is what DSPLOGBRM shows:

Date sent Time sent Message
5/18/10 3:08:13 Starting save of list SAVELIST to devices TAPMLB04.

5/18/10 4:45:58 Save of list SAVELIST complete.
As you can see, all the library saves reported the same start and stop
times. A question: are these times the same because these four libraries
(excluding QGPL) are in the same step? The control group step in question
is:
30 SAVELIST *OBJ *SYSBAS

...with SAVELIST defined as:
10 VNGDBDTA *ALL *ALL *ALL
20 VNGCUSDTA *ALL *ALL *ALL
30 PROD_MOD *ALL *ALL *ALL
40 PROD_DTA *ALL *ALL *ALL
50 QGPL *ALL *JRNRCV *ALL

Do I need separate steps to accurately track the save times?

We are on a 9406-810. The spend here is tight, and there is talk to moving
to a big-name TLA (not IBM). Upgrading the tape library will probably not
happen.

Thanks,
Loyd

What is showing in the History Log. Typically there is a message posted
there for each library saved. I don't know what system you are running

but

stepping up to a LTO2-4 using the LVD interface should speed things up

too.

In BRMS, is there a way to determine the actual time it took to save a
library?

In our daily backup, we perform a full save of four main libraries to

tape.

They all start within a couple of minutes, and end 90 minutes later.

Here

is
a partial list of the media information report (entries before and

after

these five are excluded):

Saved Save Item Save Save Expire Objects
Item Type Type Date Time Date Saved
VNGDBDTA *FULL *LIB 5/18/10 3:08:17 6/08/10 6398
VNGCUSDTA *FULL *LIB 5/18/10 3:10:23 6/08/10 35
PROD_MOD *FULL *LIB 5/18/10 3:10:24 6/08/10 2266
PROD_DTA *FULL *LIB 5/18/10 3:11:15 6/08/10 117
QGPL *FULL *LIST 5/18/10 4:40:02 6/08/10 68

The tape drive is single LTO1 (3581). We are V5R4. (Unfortunately, we

have

vendor software issues - sitll! - that prevent us from moving to 6.1.)

Our current save strategy is to save the enitre system on Sunday, then

save

specific libraries (full save) during the week. In the event of a

disaster,

we only need a Sunday tape and the most recent daily tape. Other

libraries

not saved daily were determined to be of low risk.

We are looking to reduce our current backup window.
