Re: [ADSM-L] altering dsm.sys right before dsmc

Hi Mario,

Some comments:

* Why exactly are you doing this? Why not let incremental backup just back
up new files in the /backup/rman/full/ directory structure? Do you
anticipate unwieldy amounts of data? As someone else pointed out, you will
eventually have a mountain of virtualmountpoint statements in your dsm.sys
file. So best to understand first if this is really what is needed to get
the job done.

That having been said...

* Note that DOMAIN is "additive", meaning that it is added to whatever is
already in your client option files and server-side client option set.

* You cannot use wildcards in DOMAIN.

* If you add a virtualmountpoint option for the directory then it should be
sufficient do just do:

   dsmc incremental /backup/rman/full/xxxxx >> /backup/tsmlogs/$ARCHLOG

where xxxxx is the "$DATA" date. And you get valid last backup start and
end dates on your file spaces, whereas you do not when doing a wildcarded
backup.
