Hi Rick,

The incremental backup in TSM is the best solution to optimise the database
size, instead of doing daily selective.
When you want to do the incremental backup in an seperate diskpool create a
new management class will the appropriate backup attributes and specify the
storage destionation to you new diskpool.
Specify the list of files to backup in the dsm.sys file using the inclexcl
option.


The option DIRMC is used to specify to which management class does the
directories should be backuped, not the files.  If you donot specify this
option(DIRMC)directories will be automaically
backuped by TSM to the Management class which has the higher retention in
the activated policy set.

Hope you understand ....

I feel silly asking this question but I know the answer would be known to
you all.  My company does mainly full/selective backups and does not use
incrementals.  I recently wished to change this policy to take advantage
of TSM's ability to handle incrementals (besides our tsm DB is getting
large).  We do incremental backups of a flat file database to disk and
those expire after a period of one day.  This is a "just in case" backup.
I wish to do incremental backups but to a different disk pool.  I just
read about an option that can be put in the dsm.sys file DIRMC.  Would
this be the option I need for placing my incrementals into a different
management class (ie .. different disk pool)? I say yes but I would like
confirmation.  The other question that I have is that in planning for a DR
do I just follow the old rule of incrementals daily and a weekly
selective and if you have a disaster get the weekly and the incremental
and restore.  I know none of you know what are retention or backup
policy's are but I want to know if this jives with the "normal" TSM
procedure or if there is a better way that I am not aware of.  The classes
dont cover policy's very well and what is the best method so im relying on
everyone's experience here.

Thanks for the assistance all,
Rick.
