I believe the space requirements matter on what type of hotbackups you will be doing.

If you are using RMAN, then see Getting started with Recovery Manager - it shows the space needed and how to set up/decided what you would need.

Other 'home grown' scripts I've seen will either go to disk (compressing on the way so not as much disk space is needed) or straight to tape. The one constant is that the export only grabs what is actually being used from the database - it does not require the physical size unless your database is at 100%.

As far as your first question the answer seems to be " it exports the db and then you backup the exported files." is the normal way of doing it.

Your best bet is to get with your Oracle DBA and work out the needs of the application.

nnspew

NNSPEW(8)						      System Manager's Manual							 NNSPEW(8)

NAME

       nnspew - subject database manager (nn)

SYNOPSIS

       nnspew

DESCRIPTION

       nnspew builds a sorted database of all available subjects in the nn article database for fast access via the nngrab utility.

       nnspew should be activated regularly to rebuild the subject database, e.g. by cron.  For example:
	  2 6,9,12,15,18,21 * * *  root /bin/nice /usr/lib/nn/nnspew

       Cross  posted articles are only represented in the database once, and identical subjects in each group are merged into one to use a minimum
       of disk space.  This saves about 50% of the disk space otherwise required.

FILES

       $db/subjects   subject database

SEE ALSO

       nn(1), nngrab(1), egrep(1)

NOTES

       nngrap will use the subject database generated by nnspew independent of its age.  Thus, if you stop running nnspew, remember to remove  the
       subjects file as well.

BUGS

       nnmaster  should automatically append new articles to the subject database to keep it up-to-date, and thus require less frequent rebuilding
       using nnspew.
