Subject: Re: Backing up a large file system for a TSM newbie
I have file systems with 1.5TB and 9 million files. They do take a while to
backup. We can save a 1 TB SAP database in about 2.5 hours. So, I think we
need some more information.
What kind of tape?
What kind of disk?
TSM server on AIX?
What kind of Network interface?
What does your dsmserv.sys and opt and dsm.sys and dsm.opt look like?

try with the adaptive sub-file differencing incl. in the 4.2 Client If you
have enough capacity in the network components the ressourceutil param in
the dsm.opt or dsm.sys may also help regards joachim

Betreff: Backing up a large file system for a TSM newbie
Hi,
sorry if this is a repost!
firstly let me state that I am very new to TSM and have only picked up
bits and pieces from reviewing the list and some FAQ type docosso pls
excuse if this is a basic question...
We have several AIX boxes which have 'large' file systems...by large I mean
30Gig which contain multiple installs of Oracle sever s/w so
thousands
of files/directories. (NB Not the database files them selves)
A selective backup of these is taking a 'significant' amount of time -
approx 4 hr to do a filesystem of about 35G...I have tried going directly to
tape - think it was even slower
so what I am looking for is some advice on the best settings for these types
of file systems
TIA
Peter
