After posting the query below, and receiving several useful
responses, I have disabled the automatic Catalog backup, and instead
added a brief cron job (on the Media Server where my catalog tape lives)
to run the bpbackupdb command every morning.
This works like a charm, my backups aren't delayed any more, and the
Catalog backup itself runs more quickly. Thanks to all who responded; I
am very grateful.
P.S. Dan Logcher of MIT suggested _also_ using rsync to pull a copy of
the Catalog to a DR server after the backup-to-tape, which I like. (See
the list archives for details.) Those MIT guys are as smart as I have
