If you go straight to tape, until the second copy of data is made, you have
a single point of failure.

        Hallo,

             I felt equal and defined one storage pool (family) per
plattform. I
        don't use disk storage pools, only tape and copy stgpools.

        Another way is to use collocation to separate data. I use this only
for
        special cases (such as databases).

        Greetings

        Thema: TSM configuration questions




        I am setting up TSM in our shop and I am learning TSM
        as I go. Right now, I have set up a 100GB Disk Pool
        and one Tape Pool and one Tapecopy pool for making
        offsite storage copies.  My questions are:

        If I am doing backups using this configuration, my
        daily backups on NT, Netware, and Unix will all first
        go to the disk pool and then migrate to the tape pool.
         Data on the tapes will consist of information from
        all platforms, mixing together, right?  I was
        uncomfortable
        with this data mixing idea.  I called TSM support and
        they assured me everything would be alright.  However,
        If I still want to have tapes consisting of only one
        platform only, are there ways to configure the system
        to do that?  My purpose of doing this is to have NT,
        Novell, and Unix System Administrators to handle their
        own tapes.

        Any ideas or suggestions would be greatly appreciated.
