Re: BRMS sometimes saves entire IFS

<LOL> You and me both, Kevin. I read that several times this morning
and even got a cup of coffee and tried again, but I couldn't find any
explanation in there either.

That seems to talk about when it decides to do a full or incremental,

but I must be dense today. It doesn't seem to me like it explains how it
decides.

Yes, we're researching reducing SAVSECDTA time. That will involve

that project hasn't been scheduled yet. This IFS issue is a different

looking at the logs, I don't understand it at all.


We've got this in our backup:


Auxiliary Weekly Incremental Full Retain

Save List Storage Activity Media Media Object

Item Type Pool Device MTWTFSS Policy Policy Detail

*LINK *ALLAVL IIIIIFI DAILY DAILY *YES


But from what I can tell, the system did a complete IFS save on 3/23,

3/27, 3/30, 4/06, 4/10, 4/13 and today, 4/17. I only base that on the

number of IFS objects saved (2 million vs a few thousand). I cannot

tell from the logs which type BRMS attempted. Weirdly, it doesn't seem

to me that it is EVER doing a complete IFS backup on Saturdays (3/21,

3/28, 4/4, 4/11).


4/13 was unusual in that it was an ad-hoc mid-month save during the

day. The rest all occured during our overnight processing, in which the

IFS *LINK portion usually kicks off around 2AM (unless SAVSECDTA goes

long).
