[Veritas-bu] Catalog Backups

Historically, when a Catalogue Backup took place (either via the internal
scheduler or manually), all job/activity had to cease -- hence no jobs could
be running.  I've recently been told that this is no longer the case --
possibly with a patch to 3.2?  Does anyone know whether this possible, and
what level you need to be at?

Thanks,

Mike
