Backing up multi-version releases

Now that the dust has settled after our upgrade to 6.5.4, I've been
studying the changes in the file structure for the server to support
multi-versioning.  I want to make sure that I'm still backing up all of the
necessary files.

I'm sure there are much more sophisticated backup strategies available, but
I'm using a simple CL to end the server, write the files to savefile,
restart the server, then write the savefile to tape.

Currently, I'm saving the data directory from my server (where the
databases are stored), /QIBM/UserData/Lotus/*, and the QNOTES and QUSRNOTES
libraries.  In the redbook Installing and Managing Domino for 6.5 for
iSeries, it indicates that "backing up all Domino databases" simply
requires the data directory and /QIBM/UserData/Lotus/Notes/*.  Apparently,
QNOTES and QUSRNOTES are part of the "program libraries" -- so should I
drop them from my backup?

I'm looking on pages 133 - 135 if anyone wants to see what I'm talking
about.

Also, my iSeries resource guy indicated that if we had a disaster and
needed to recover the entire Domino server (but not the iSeries) that we
could delete the Domino libraries and folders, re-install the server
software, and restore our backup.  By Domino libraries, I'm expecting it to
be all those listed on page 133 of the redbook stated above.  Is this a
wise approach or are we asking for trouble?

Thanks,
Patrick
