backing up sipb cell to two tapes

Since we seem to have more than one tape's worth of backup volumes in
the sipb cell now, I backed up the volumes on ronald-ann and rosebud
separately onto two tapes.

This involved adding two new volume sets to the backup database: rann
and rbud (the previous volume set, sipb, is still there). Also, eight
new dump levels were added: /rann_{1,2,3,4} and /rbud_{1,2,3,4}.
Again, existing entries (/full_{1,2,3,4}) were not removed.

We didn't seem to have any program to do "vos backup" on the backup
volumes from a single server, so I wrote a script "mkvbscript" (see
below); there are some comments saying what it's supposed to do.

So, a working backup procedure now would be something like:

   1) Choose an appropriate tape and make sure it has the label you
      want. I relabed sipb.full_4.1 to rann.rann_4.1; you might want
      to follow this pattern for future ronald-ann backups. Note that
      sipb.full_1.1 is currently stored with IS Dispatch in Building 11.

      For rosebud, I used one of the QG112MA tapes (these are the $15
      ones, versus $6 for the regular tapes). If we decide we need to
      use a full set of four of these, then we'll have to ask Kathy
      Allen for yet more tapes RSN.

   2) cd /afs/sipb/project/newdump
      scripts/mkvbscript servername
      script vb-script.server_abbreviation.YYMMDD
      /usr/tmp/vb-script.servername.DDMonYYYY
      ^D
      compress vb-script.server_abbreviation.YYMMDD
      mv vb-script.server_abbreviation.YYMMDD.Z last/

   3) Run the usual backup.pl script with -noclone, e.g.,

      /afs/sipb/project/newdump/backup.pl rann /rann_1 -noclone

marc: If it seems reasonable to do the backups on a per-server basis,
you might want to call mkvbscript from backup.pl, or otherwise
eliminate step 2.
