My assumption was that having seperate filesets would cause it not
to see them as the same files - thus the tape backups would not be
considered as part of the ondisk backups.

In our scenario, that's fine.  We want the ondisk backups to work
independently of the tape backups, since the tapes are archived off
site.

My concern about duplicating the filesets is twofold:
1) Error-prone when changes are made (i.e. machines added/removed)
2) namespace pollution (i.e. when doing a "run" from bconsole)
   and the possible human errors involved with such pollution.
