We reluctantly employ a selective backup of certain directories on certain
servers in a regular fashion in order to facilitate a slightly quicker
recovery.
The mentality is that you can recover quicker as it is more likely that your
data will be spread out across fewer tapes.

The problem though is that many of our customer can't understand adsm's
incremental forever architecture and insist on the full backup.

In actual fact I doubt whether our this selective strategy will really buy
us much more than 10 or 20mins. If you have a fully automated library
requiring no manual mounts it's probably not worth it at all.

        Subject:        selective backup prior to client maintenance?

        ADSM employs an "incremental forever" backup paradigm.  However,
we'll be
        performing maintenace on a client this weekend, and so the there
will be a
        increased risk of data loss.  Would it be prudent to take a
selective
        rather than an incremental backup in anticipation of that
maintenance?  Has
        anyone adopted this practice?

        Thanks.
        Mark.
